Purchase individual HMCUs that work with ACK

If you purchase an Espressif ACK development kit, you must purchase an HMCU separately, such as an Arduino Zero or another supported development board.

Note: The getting started and other examples in this documentation use an Arduino Zero development board to represent an Host Microcontroller Unit (HMCU). If your ACK development kit doesn't come with an Arduino Zero development board, and you want to complete the getting started examples, purchase an Arduino Zero development board.

Purchase an Arduino Zero

The following table contains links to the Arduino Zero development board available for purchase.

Purchase an additional Host Microcontroller Unit

You can also build ACK devices on other commercially available HMCUs instead of the Arduino Zero. For an updated list of additional HMCUs that you can use, see ACK HMCU Development Kits.
