    Sendcomm-0.9.4

    michael 4 years ago 34 commits to master since this release

    Description

    This release marks improvement of design work on Microchip SAMR34 architecture hardware circuits and firmware samples.

    Assets

    Files terminating with .bin in the firmware archive are Cortex-M0+ binaries to program the SAMR34 chip using a SWD capable debugging device on connectors J4 and J20.
