  2. Neoway SL720 433MHz

    Schematic for cheapest (10$) Neoway LORA module SL720 . Firmware for P2P mode Firmware for STAR mode...

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

    UPDATE: Range for wire antenna 17cm 433MHz, LORA mode. Software based on Radiohead (see below) with STM32L151. Minimum RSSI -84 dB for 450 meters (across building). UPDATE : Implement standalone datagram server and client from Radiohead 1.46 Support USB-CDC and Serial communication. Source codes available on github Simple LORA RF module with RF96W/RF98W (HopeRF) and STM32L151CB. Configuration via soldering jumpers for USB, standalone or Raspberry PI. Software from LoRaMac-node...

  4. Router device (continue EzMacPro - STM32 & EFM32)

    First post about small device for home automation and meerkats control station. Test only with RFM22B and STM32F103CB. https://github.com/x893/EzMacPro32 Now device photo and complete in a box Now i use STM32L151 (5-6uA in sleep mode) but also test EFM32 (2 uA sleep). Ported EzMacPro stack provide P2P network (many base stations with many end-devices) or star (single base station) network. I plan use for home automation, simple car show control system and for wild animal control application. Build-in accelerometer provide device self control for movement (legal or not). Together with microSD device...

  5. Program CC Debugger (CC2511) with Arduino

    After soldering module CC Debugger (last module) i need to program internal flash with TI firmware. I havn't any TI development tools and decide use Arduino for program. Repository contains PDE file for Arduino and C# project for front-end on PC. First step - connect 3 wire from arduino to CC debugger: PD5 > CC DC line PD6 > CC DD line PD7 > CC RESET line and write sketch to access CC lines from host computer via serial port. Second program on C# to work with CC memory via Arduino and write original TI bootloader for CC debugger (converted to binary format) Third step write original...
