About Product

Introduce

Maduino Zero HM-13 is an IoT (Internet of things) Solution based on the 32-bit Atmel's SAMD21 MCU and Bluetooth module HM-13. It integrated a micro Controller ATSAMD21G18, BLE module HM-13. The Maduino Zero HM-13 based on the Arduino, users can program it with Arduino IDE, which is very easy especially suit for the none-programmers. There are also guide for users to learn how to create the first IoT project with this board, with which the starters can learn the hardware and programming skill quickly. With this board, you will easy to add text, SMS, and data to your project. It is good for your smart home project or M2M and so on.
Model: OAC013HMB

  • After uploading successfully, remove the SD card to the PC.
  • Check that there is a file “test.txt” in the SD card, and the file content is “testing 1, 2, 3.”, which provides the SD card can be read and written.

Bluetooth test

  • The program for setting the Bluetooth can be obtained from Github.
  • Open the program by the Arduino IDE, and select the board and port.
  • Install the library for HM-13 module.

  • The Bluetooth name of the BLE mode or EDR mode can be modified in the code.
// BLE and EDR device names      
String edrName = "MyEDR";      
String bleName = "MyBLE";
  • Upload the code, then reset the board.
  • After a few minutes, you can find the Bluetooth with the name by using another device.
  • Use a Bluetooth debugging tool(such as nRF Connect) to connect the Bluetooth. Send a message to Maduino Zero HM-13 and the serial monitor will display the received.
