Ebyte E80 Module Development Board (HF)

Overview

E80-xxxMBL-01 series evaluation kit is designed to help users quickly evaluate Ebyte’s new generation LoRa dual-band wireless module. The board is equipped with a STMicroelectronics general-purpose MCU STM32F103C8T6, and most of the pins are led out to the pin headers on both sides. E80-900MBL-01 features a Ebyte E80-900M2213S module with a Semtech LR1121 modem and is configured for High Frequency LoRa bands (868MHz, 915MHz, etc) and the 2.4GHz LoRa band.

Hardware

E80-900MBL-01 provides the following hardware components:

  • STM32 microcontroller in LQFP48 package

  • Three LEDs:

    • User LED 1 (LED1), User LED 2 (LED2), power LED (PWR)

  • Three Buttons:

    • Reset Button (RST), User Button 1 (K1), User Button 2 (K2)

  • CH340 USB to UART adapter.

  • E80-900M2213S Module, featuring semtech LR1121, configured for 850-930 MHz and 2.4GHz LoRa.

Programming and Debugging

The e80_900mbl_01 board supports the runners and associated west commands listed below.

flash debug

Applications for the e80_900mbl_01 board configuration can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

Flashing

The e80_900mbl_01 board uses the SWD debug port that is broken out to an header for flashing.

Flashing an application to E80-900MBL-01

Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b e80_900mbl_01 samples/basic/blinky
west flash

You will see the LED blinking every second.

Debugging

You can debug an application in the usual way. Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b e80_900mbl_01 samples/basic/blinky
west debug
