New Open Source Hardware board ESP-PROG allow you to program any Espressif device and can be used as general purpose USB-Serial converter

Created with GIMP

ESP-PROG is USB to Serial converter but beside the Serial TX and RX signals it also can power the target with +5V up to 0.5A or 3.3V up to 0.5A and have two additional signals which make programming automatic RESET (EN) and BOOT enable.

ESP-PROG-C includes all necessary cables for the ISP programming – 7 pcs jumper wires female to female and 6 pin ICSP cable.

ESP-PROG is based on CH340T IC and has drivers for Linux, Windows, MACOS, Android with up to 2 Mbps speed.

Open Source Hardware Industrial Linux computers STMP1-OLinuXino-LIME2 prototypes are ready for testing

STMP1

First prototypes of the Open Source Hardware Industrial grade operating at -45+85C Linux Single Board Computers STMP1-OLinuXino-LIME2 are assembled.

STMP1a

We build couple of boards with STM32MP153 and STM32MP157 for the first tests.

Now time to add Linux mainline support for it in OLIMAGE building and to add Ubuntu and Debian minimal and base images for it in http://images.olimex.com

Industrial grade -45+85C STMP1-SOM is almost completely routed and pin to pin compatible with A13-SOM

STMP1_SOM_bot

A13-SOM-256 and A13-SOM-512 are low cost Linux running System on Modules which are very popular but lack industrial grade operating temperature.

STM32MP1XXX series of SOC from ST is the first mass produced SOC which operates from -45 up to +125C by default, so we decided to design SOM module with STM32MP1XX SOC which to be pin to pin compatible with A13-SOM and offer same interfaces and signals so it could be drop in replacement for A13-SOM without need to re-design the complete product.

As you can see for STMP1-SOM we decided to put the SOC on opposite side of the connectors, this allow if necessary to add aluminum heatsink without interference with mainboard.

STMP1-SOM_TOP

Also we add AXP209 PMU which allow lower power operating modes and LiPo battery backup and operation on battery only which is missing in the original A13-SOM.

STMP1-SOM will be offered with three SOC choices STM32MP151, STM32MP153 and STM32MP157.

The prices will start from EUR 15 for the non industrial grade memory which are similar to A13-SOM and EUR 18 for the industrial grade -45+85C memory version.

We expect first STMP1-SOMs to be available in July 2020.

Full mainline Linux support will be available at http://images.olimex.com/

New open source hardware board ESP32-S2-DevKit-Lipo breaks our internal record for ESP32 low power consumption

Screenshot from 2020-05-18 11-46-43

ESP32-S2 is new SOC from Espressif which has only WiFi connectivity but has much more GPIOs available than ESP32 and ESP8266, also it has USB native connection which opens lot of new possibility.

We already sell Espressif’s Saola-1R board which has ESP32-S2-WROVER module, but it’s not designed for battery operation and low power as uses general purposes LDOs and has no battery connection.

This is something we wanted to improve – we designed board with same module but add LiPo charger and now our ESP32-S2-DevKit-LiPo can operate on LiPo battery even when there is no external power supply, but on top of this we kept the same PCB dimensions and ESP32-S2-DevKit-Lipo is drop-in replacement for ESP32-S2-Saola-1R. We use same module with 2MB RAM and 4MB Flash so once you develop with Saola you can move to ESP32-S2-DevKit-Lipo and make your projects battery operated.

The new ESP32-S2-DevKit-Lipo uses ultra low power power supply circuit which makes current consumption during sleep only 6uA  (4uA of them are due to the battery measurement resistor divider) this is 10 times less than our other boards.

Prototypes are build now and we run production and will have these in stock by the beginnings of June.

PIC32-Pinguino Open Source hardware board is on the cover of Electronic music vinyl

Screenshot from 2020-05-18 09-00-50

We got note from friend that our PIC32-Pinguino is on the cover of Belgium artists Phillipi & Rodrigo – “Gueto De Gent” Vinyl album. The genre is Electronic/Disco. You can hear it here:

 

Maybe the authors are also Makers and like to make electronic projects?

 

ESD safe, powerful 65W soldering iron with LCD display, digital PID temperature adjustment 250-480C in stock

ATN-ST2065D

ATN-SLD2065D is professional grade, powerful 65W soldering iron with digital PID temperature control and ceramic heater element for fast heating. Build in motion sensor enter sleep mode if the soldering iron is not moved for more than 10 minutes and completely shutdown after 20 minutes of non activity.

It has LCD display, power and +- buttons, LED status indicator and heats fast.

For these who are familiar with TS100 soldering iron,  ATN-SLD2065D is similar but with much more power and allow even bigger PTH components to be soldered quick and easy.

The soldering iron comes by default with one ATN-T900-B solder tip which is good for PTH components soldering and rework, but we also offer 4 more different tips which are good for normal and fine pitch SMT components soldering.

The ATN-T900 soldering tips are with professional grade excellent plating, which allow long lasting work, but they also are priced very competitive. For comparison ERSA and  Weller soldering tips which are with same grade plating cost EUR 6-12. We use ATN-T900 in our daily production and they are very good choice as price/performance, the normal low grade soldering tips do not last more than couple of days with intensive work at our factory. ATN-T900 lasts for about month, for the about same time ERSA/Weller tips also wear off at intensive work.

The ATN-SLD2065D-HS are ceramic heaters with long life and very competitive price,  ATN-SLD2065D auto detects broken heater and signals for exchange.

With their good pricing ATN-SLD2065D soldering iron and ATN-T900 tips are very good choice for both professional engineers and beginners.

Limited Quantity of the new ESP32-S2 multimedia and breadboard development boards from Espressif are in stock!

ESP32-S2-Kaluga-1

ESP32-S2 is new SOC from Espressif which is supposed to solve some issues with current ESP32 and ESP8266 SOC chips.

First issue S2 solves is the small number of GPIOs ESP32 has, specially if you want to use the Ethernet interface. ESP32-S2 comes with 37 GPIOs in nice 5x5mm QFN28 package. The SOC is single core 240Mhz processor with build in USB interface. The Bluetooth and Ethernet interfaces are removed.

Pricewise ESP32-S2 is cheaper than ESP32 but a bit more expensive than ESP8266.

ESP32-S2-WROOVER module comes with 2MB of RAM and 4MB of Flash and will be able to replace ESP8266 everywhere while having enough resources to run secure SSL connection.

Two development boards are available for ESP32-S2.

ESP32-S2-Saiola-1R is the low cost entry breadboard experimental board which includes ESP32-S2-WROVER module, USB programmer, RGB LED and couple of buttons.

It has all GPIOs exposed for experiments:

esp32-s2-saola-1-v1.2-annotated-photo

The second board is ESP32-S2-Kaluga-1 which is multimedia board with camera, microphone, audio codec, 3.2″ LCD with touch screen, speaker:

ESP32-S2-Kaluga-1b

The kit comes with Camera module:


ESP32-S2-Kaluga-1c

and touch sensor plate:

ESP32-S2-Kaluga-1e

Kaluga multimedia board is so new that still not have page at Espressif site, so all info is in their GitHub repository.

New Plastic Box design for A20-OLinuXino-LIME2 with LiPo6600mAh battery

PLASTIC-BOX-ASM1

Few days ago we got parcel with some plastic parts sent to us from Mike Bosschaert.

PLASTIC-BOX-ASM2

we inserted LIME2 inside, the tolerances are tight and it’s hard to put the board in but even harder if you want to pull it from the plastic.

PLASTIC-BOX-ASM3

There is place for LiPO6600mAh battery with holder, but the battery cable is too short to plug in the board connector and need to be cut and extended. If the battery is put at left side of the PCB the cable may be enough.

PLASTIC-BOX-ASM4

The assembled box looks nice! Mike wrote that he designed it with FreeCAD and the model is printed in PLA using a Felix Pro 2 FDM printer. He provided all STL files under CC BY-SA 4.0 licensee and we add to OLINUXINO GitHub repository.
