About this Gig
Hello there,
I specialize in LoRa watch firmware development using SX1276 and RFM95W modules with full SX127x driver integration. I implement secure and efficient UART/SPI LoRa interfaces on STM32 and ESP32 platforms.
RF systems are designed for 433MHz, 868MHz, and 915MHz bands with proper configuration and performance tuning. Battery charging and protection circuits using TP4056 and DW01A can also be integrated for portable devices.
Services I Offer
- LoRa watch firmware development
- SX127x driver integration
- Softball text sign controller development
- Baseball LED message board system
- OLED display (SSD1306 / ILI9341) integration
- MAX7219 scoreboard control
- RF watch remote design
- Battery charging circuit (TP4056 + DW01A) integration
Why Choose Me
- Strong experience in LoRa RF firmware development
- Reliable SX1276 and RFM95W driver integration
- Clean, optimized STM32 and ESP32 programming
