  5. EFM32 bootloader with STM32 USART protocol

    EFM32 bootloader (Olimex EFMG880F128) support STM USART bootloader protocol. Use LEUART with 9600 b/s to communicate with host. Need add one file to STM Flash Loader demonstrator Map/EFM32G880F128.STmap Source for bootloader and application example available at Github ....

  6. DIY JLink-OB-072 (JLink + COM)

    UPD: Add Eagle files Schrmatic & Board for all type of USB connectors and technology rules from Rezonit. Don't forget say thanks to SEGGER ! How to make JLink-OB-072 debug adapter. PCB with big USB, miniUSB and microUSB. Easy and correct way - buy from SEGGER and be happy. Also right way - build it yourself but with some limitation. You can't use firmware update from JLink.exe only via STM DFU utility. Now need prepare first step. Buy correct beer (Krusovice) and open it. 1. Extract binary part from JLinkARM.dll (from JLink_V512) For example from offset 7153340 (0x6D26BC) and size 41192...

  7. OpenMV

    Great project OpenMV but only need order 4 layers PCB. Redesign to 2 layers and now soldering and test. Additional PCB with 3G modem (H350) provide fully autonomous transmitter images. 3G modem now as arduino or Raspberry Pi shield but after testing make PCB within same size. 2 layer OpenMV Eagle files...

  8. Small form-factor GPS/GSM tracker

    Update: Now you can pre-order here https://www.indiegogo.com/projects/arduino-gps-gsm-anytracer New version of small form-factor GPS/GSM tracker. Real positions available as Public on test site. Change MCU to EFM32 increase standalone time (previous version use STM32 MCU) Also change old BMA180 to MMA8562 and add 32Mbit (4MB) flash chip to save data if GSM not available or battery low. Use MS Azure platform for web site and service for collect data from trackers. Based now on GL865 but with Fibocom GSM dimensions reduce from 24x24 to 24x18 mm (GPS antenna size 15x15 on my hand) Now check various...

  9. STM32 Vehicle Tracker

    Vehicle tracker with schematics and software. Updated: Cx version support direct connection GPS to GSM via wires (or change layout) so you can use buildin Python to implement tracker functions without STM32 MCU . Updated: Links to OSH Park pcb service Cx version Rx version Features: STM32 48/64 pins (F10X, F20X, F40X, L151) GSM Telit GL685/GL868 GPS/GLONASS SL868/SL869 Accelerometer MMA7455 CAN bus (need MCU with CAN support) 2 input, 1 output signal Standard SIM or SimOnChip Only for 48 pins version Side connector for extension pcb Only for 64 pins version Battery support with charger USB support...

  10. Lab power supply

    Simple dual power supply with TFT screen, bluetooth and control current and voltage. Millions thanks to http://www.maximintegrated.com/ for samples. Now it best company for sample (second TI :) ). One control board and up to 2 power supply board. and power supply based on Maxim (regulator+control+measure) all PCBs size 33x32 mm (only TFT display more but with Bluetooth control it no need) With 3 button easy to control without host All PCB connects as sandwich so i have a small cube with 33x32x30 mm for dual power with measurement and regulate dual voltage supply. Now too easy make a consumption...
