Open Source Hardware LIME2-SERVER user manual is uploaded and explains how to assembly and how to install Linux images of popular projects

LIME2-SERVERа

LIME2-SERVER is Linux server with only 2W consumption, A20-OLinuXino-LIME2 and option for HDD or SSD.

The server has bild-in LiPo battery which allow it to run for hours without external power supply, Gigabit Ethernet connection and power adapter 5V 2A.

Today we uploaded on GitHub the initial version of the user manual which explains how to assembly the boxes in case you didn’t bought it assembled.

Also basic instructions to use Ubuntu Bionic and Debian Buster images we provide.

KODI and NextCloud installation.

Additional info how to build and install Home Assistant, Yunohost, TOR server will be included in the next revision.

The LCD-OLinuXino Selection guide now includes the LCD panel dimensions and thickness information.

BAY-HDD/SDD is easy way to add external storage to LIME and LIME2, now Pioneer-FreedomBox-HSK can have 2000GB external storage in robust enclosure

LIME2-SERVER8

BAY-HDD-500GB, BAY-HDD-1000GB, BAY-HDD-2000GB and BAY-SSD-512GB are external disks with special bridge board to plug in A20-OLinuXino-LIME and A20-OLinuXino-LIME2 servers providing all necessary connections and power supply for external disk.

It’s plug and play recognizable by Pioneer-FreedomBox-HSK and adds significant amount of storage to the platform.

 

New useful parts for OLinuXino OSHW Linux computers, soldering tool and new components in stock

USB-RS485-wiring

USB-RS485 is USB to RS485 converter and can be used with any computer with USB including OLinuXino.

A20-OLinuXino-MICRO, A64-OLinuXino, A13-OLinuXino, A33-OLinuXino, iMX233-OLinuXino have Audio input, for these boards we got very compact and flexible PC-MIC-3.5MM

For these who deal with tiny SMT parts we got stackable X*Y smt SMT-BOX-25x32x22 with spring loaded cap:

smd-smt-box

SLD-SPONGE is soldering tip cleaning sponge:

SLD-STAND is metal stand for soldering irons with place for soldering sponge:

SLD-STAND

CONNECTOR-GX16-4 is robust connector for panel mounting and can connect up to 220V/20A:

GX16-4

WIRE-CLIP-300F is female connector at one end which easy connects to boards with headers and sprint loaded contact at the other end. If you make signal analyzer with FPGA boards these clip wire connectors are very handy to attach to existing boards:

WIRE-CLIP-300F

ALUMINUM-HEATSINK-TO-220 is low cost heatsink for TO-220 devices like voltage regulators and transistors:

ТО220

 

 

New Product in stock: Metal box for A64-OLinuXino

BOX-A64

BOX-A64-BLACK is metal box with PVC black coating for A64-OLinuXino

The box comes with all necessary fasteners for board assembly inside the box and four rubber feets.

Opening for external antenna is provided although current A64-OLinuXino revision has no WiFi module with U.FL connector inside. We work on next revision where this will be fixed and A64-OLinuXino board will be possible to order with internal or external antenna.

 

Say Hello to Es-Ti-Em-Pai STMP1-OLinuXino the Open Source Hardware with mainline Linux support and -40+125C operating temperature

Screenshot from 2019-12-10 08-05-45

ST32MP1XX SOCs from ST Microelectronics has one unique feature: They operate from -40 up to +125 by default there is no other commercial or industrial or etc temperature range. What does this means – very well done production! It’s not secret that all SOC vendors produce their chips then test them and which pass -40+125 are classified automotive grade, which fail but pass -40+85C are classified industrial and it there are SOC which fail both automotive and industrial grade on tests are sold as commercial grade.

This chip has no other than automotive grade, so ST is confident in their process quality.

For this SOC ST Microelectronics guarantee 10 years rolling availability.

The peripherals ST32MP1XX has are also industrial and real time oriented:

  • Cortex-M4 co processor, we know Cortex-A series when run RTOS has latency which do not allow fast processed like motor control etc. This is where this co-processor release the main OS processor of such demanding tasks
  • FD-CAN ST32MP1 has two cans both support FD which offer less latency and faster speed, one of them has also time triggered CAN (TTCAN)
  • 2 × ADCs with 16-bit max. resolution (12 bits up to 4.5 Msps, 14 bits up to 4 Msps, 16 bits up to 3.6 Msps)
  • 2 × 12-bit D/A converters (1 MHz)
  • 8- to 14-bit camera interface up to 140 Mbyte/s
  • Gigabit Ethernet
  • 6 × SPI (50 Mbit/s)
  • 6 × I2C FM+ (1 Mbit/s, SMBus/PMBus)
  • Documented Trust Zone and Secure Boot (may be subject to some export restrictions)

We designed our STMP1-OLinuXino to be with same layout as A20-OLinuXino-LIME2, with all connectors on same positions, so people who used LIME2 to may migrate to STMP1 if necessary.

We put the SOC on bottom this time to may attach easier bigger heat sinks or even connect it to the BOX-LIME-BLACK metal and remove the need for aluminum heatsink.

Note that schematic is not verified yet and the PCB is not routed, we just placed the components on their approximate locations.

All preliminary files are put on GitHub so people who are interested how we wired the GPIOs to match LIME2 functionality and existing customers find potential conflicts with their current design may signal while still routing is not complete 🙂

Looking forward for your comments.

KODI pre-build images are now on on our ftp, A20 HDMI audio patches will be ready soon

kodi

Few days ago I blogged about the KODI build scripts for A20 and A64 OLinuXino ad promised pre-build images on our server. This is now done and the images can be downloaded from our ftp for A64 and A20.

A20 HDMI audio currently do not work, but Dimitar and Stefan work on this and they say this will be fixed soon. So crossing fingers we may have good news for Christmas!
