iCE40HX8K-EVB OSHW FPGA board is in stock

iCE40HX8K-EVB-1

iCE40HX8K-EVB is upgrade of our iCE40HX1K-EVB with more logic cells FPGA so bigger Verilog projects could be synthesized.

GPIO1 34 pin bus is same as iCE40HX1K-EVB and all DAC, ADC, IO, etc modules are compatible, on top of this there are plenty of additional GPIOs on 4 40 pin 0.05″ step connectors.

512KB fast SRAM is on board, with iCE40-IO board you  can connect VGA monitor and PS2 keyboard, so you can make your own custom CPU (for instance RISC-V) computer with monitor and keyboard.

  • AXP803 PMU with Lipo charger and step-up
  • 1 or 2GB or DDR3L @672 Mhz
  • 0 / 4 or 16GB of industrial grade eMMC
  • SPI Flash in SO8 package with hardware WP (not assembled)
  • USB-OTG and USB-HOST
  • HSIC connector (not assembled)
  • Gigabit Ethernet
  • BLE/WiFi module
  • HDMI and MIPI display connectors
  • microSD card

  • Audio In and Out
  • LCD display connector
  • GPIO 40 pin connector (not assembled)
  • UEXT connector (not assembled)
  • 5V power jack
  • Dimensions: 90×62.5 mm

For the moment we have three models:

  • 1G0G with 1GB RAM, no Flash, no WiFi/BLE
  • 1G4GW with 1GB RAM, 4GB eMMC and WiFi/BLE
  • 2G16G-IND with 2GB RAM, 16GB eMMC with industrial grade components -40+85C

The optional connectors and SPI Flash etc may be assembled upon request for small fee.

Sneak preview of new OSHW IoT board: ESP32-Gateway

ESP32-GATEWAY

ESP32-EVB really took us lot of time to complete mostly due to the not so complete documentation around Ethernet and our own silly errors. Also we wanted to add so many interfaces there to may people evaluate them all: Ethernet, CAN, Infrared, Relays LiPo UPS etc etc and the board become 75×75 mm. The price also went from EUR 22 to EUR 26.

In parallel we quietly were working on stripped version named ESP32-GATEWAY, as the name says we wanted just to keep here the connectivity: WiFi, BLE, Ethernet, USB for programming and micro SD card.

All available GPIOs are made on 0.1″ step strip at the bottom of the board, and two nice mount holes:

ESP32-GATEWAY-1

Today we assembled the first prototypes and we will test tomorrow. If everything is OK we will run production. We already have 100 blank PCBs ready as after so much time spent on ESP32-EVB we do not expect any troubles, but still wanted to reduce the risk to throw in the garbage bin more than 100 boards if we missed something.

So hold your breath if everything is OK we will have 100 boards for sale next week 🙂

The price of ESP32-Gateway will be EUR 22.

A20-OLINUXINO-MICRO now available also in Industrial temperature grade -45+85C

A20-OLINUXINO-MICRO-EMMC-3

We are selling for some time already A20-OLinuXino-MICRO Rev.J where few things were improved:

  1. We changed the LAN PHY from Realtek to Microchip as latter is more reliable supplier for both commercial and industrial temperature components, we searched desperately Realtek PHY in industrial temperature grade but without success.
  2. We extended the input working voltage from 6-16VDC to 8-24VDC
  3. We changed the NAND Flash to eMMC (but old NAND style flash is still possible to assembly)

The Ethernet PHY change requires new patches on the Uboot and Linux images which are already uploaded.

ESP32-EVB our new board for IoT first prototypes are ready

esp32-evbesp32-evb-2

ESP32-EVB is our new board with ESP32-WROOM32 module. It has:

  • ESP32-WROOM32 module
  • two relays 10A/250VAC
  • Ethernet 100Mb interface
  • LiPo charger and step up converter allowing ESP32-EVB to run from LiPo battery
  • microSD card connector
  • two user buttons
  • UEXT connector to attach different sensors and modules
  • 40 pin GPIO 0.1″ step connector with all resources of ESP32
  • 5V power jack
  • three mount holes

Now time to write some examples and if everything works to launch production.

The sale price will be EUR 22.00

ESP32-CoreBoard is sold out, ESP32-EVB design has started

esp8266-evb-bat-1

ESP32 is really hot, the first lot we got sold out for couple of days. If we didn’t put the restriction for one module per order it would be sold out in matter of hours, as people wanted to buy x5 and x10.

ESP32-WROOM-32 modules are shipped from Espressif and we wait them to arrive next week.

Meantime we started the design of our ESP32-EVB board.

What we think so far is to have these features:

  • power supply from 5V
  • LiPo charger and step up converter to allow un-interruptable power supply
  • Two relays 220VAC/15A
  • Two user buttons
  • UEXT connector to which you can connect many of our sensor UEXT boards, or to program the board with serial cable same way like ESP8266-EVB
  • status LEDs

With the two relays you will be able to switch on and off two different appliances.

With the sensors on UEXT you will be able to measure temperature, light, moisture etc. and log them.

The plan is to complete the design in October and start selling this board in November.

Our target is to release this EVB for EUR 15.00.

If you think we should add something else let us know.

iCE40HX8K-EVB OSHW prototypes are ready to test

iCE40-8K

What you see is our new iCE40HX8K-EVB prototype.

It has same layout as our first iCE40HX1K-EVB board with same 34pin bus connector where iCE40-IO, iCE40-DIO, iCE40-ADC and iCE40-DAC modules could snap together.

We made all connections backward compatible so all code for 1K will work on 8K too. just here you have much more resources and more GPIOs which are wired to 4 small 40 pin 0.05″ step connectors. These can be connected to external boards either with cable either with female matching connectors which are in our shop.

Now we are testing for silly mistakes, if everything is OK will run it in production next month.

The price will be EUR 39.95
