I will program and design GSM, gnss rf pcb using sx1276, sim986, mc60

Hello,

I provide advanced embedded systems design, RF PCB layout, antenna design, and firmware programming for modern IoT and communication devices using industry-standard modules such as SX1276 LoRa transceiver, SIMCom GSM modules (SIM868 / MC60 / similar), GNSS positioning systems, and WiFi-enabled embedded platforms.

What I Offer

• GSM/GPRS PCB using SIM modules (SIM868 / MC60 or similar)
• GNSS/GPS tracking PCB for location-based systems
• LoRa RF using SX1276/SX1278 modules
• WiFi & IoT PCB design with optimized antenna layout
• RF circuit design with impedance-controlled routing
• Multi-layer PCB layout (optimized for performance & manufacturing)
• Schematic design + BOM + Gerber files ready for production
• Embedded firmware for ESP32, STM32, Arduino

 Tools & Technologies I Use

• Altium Designer / KiCad / EasyEDA
• STM32CubeIDE / Arduino IDE
• ESP-IDF (ESP32 development)
• RF simulation & PCB layout best practices
• Datasheet-level component integration
