most of you know that there are plenty of ARM powered development boards out there, so you may not be really sure what a new one can still bring to the table.
With a $5 price tag, the open hardware McHck (pronounced McHack) is meant for quickly building projects on a small budget. The board created by [Simon] is based on a Freescale Cortex M4 microcontroller, and can be plugged directly into one’s computer. As a direct Firmware update (DFU) bootloader is present on the microcontroller, there is no need for external programming equipment.
The board has unpopulated footprints that allow users to add other functionalities that may be required for their future projects: a real Time Clock (RTC), a boost regulator for single cell battery operation, Buck and linear regulators, a Lithium Polymer (LiPo) battery charger and even an external Flash storage.
The Bill of Materials can be found on the project wiki and the McHck community will soon launch a crowdfunding campaign to send the 5th version of the board to all the hobbyists that may be interested.
And if you’re curious, you can also have a look at all the other boards that Hackaday featured these last months: the browser based IDE arm board, quad-core ARM dev board and the Matchbox ARM.
