After exploring a few random online shops one day, run across a very interesting development board EFB-REV1.it is a Free RTOS dual-core 32-bit CPU, 520 KB SRAM,4 MB Flash Memory, CPU operating at 240 MHz. EFB-REV1 has inbuild Serial Interface (RS232 interface (2), I2C (1), 12 bit ADC (12), GPIOs (20)) and connectivity (Wifi802.11 abgn, Bluetooth, LoRa supported Bands 868, 915 , 433 MHz).

  • The EFB-REV1 boots up in less than 200ms.
  • Provides a powerful and flexible selection across the full spectrum of application.
  • Build in LoRa module suits it perfect for application like smart metering, Automation and Industrial solution.
  • Documentation hardware and software customization completely supported by our team
  • Power supply and USB cable provide along with box for debugging.
