MC HCK US$5 development board (some assembly required)

johnbeetem

I just saw this at Geek Times: Build Your Own Development Board for $5.  MC HCK (pronounced McHack) is a tiny microcontroller board with a Freescale MK20DX32VLF5 (ARM Cortex M4 with 8KB SRAM, 32KB Program Flash, 32KB Data Flash, USB, I2C, SPI, UART, I2S).  You can program or use it as a USB dongle and it has an array of DIP holes so you can plug it into a solderless breadboard.  It's so open source that you need to make and assemble your own PC boards.  MC HCK website is https://mchck.org/.

 

Very nice board size and shape IMO -- versatile for all sorts of MCU projects.

  • The only (slight) thing that the eetimes article doesn't mention is that a bootloader is initially required to be programmed in, and  that requires a programmer (many people may already have a bus-blaster or a FRDM board, or an alternative) to do this. The main article mentions this though so that's good.

    But still, it's very cheap, ideal for a very low cost, compact board!
