  1. 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 ....

  2. SX1278/SX1276 (RFM98W/RFM96W) LORA module

    Simple LORA RF module with RF96W/RF98W (HopeRF) and STM32L151CB. Configuration via soldering jumpers for USB, standalone or Raspberry PI. Software from LoRaMac-node...

  3. 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...

  4. 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...

  5. 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...
