Donate to support Open HardwareCompact, yet easy to assemble. This shield attaches to the bottom of a 3.3v Pro Mini, thereby leaving easy access to the Pro Mini's reset button. It also offers an additional 3 LED's (powered by digital pins 6, 7, and 8). It has two decoupling capacitors near the nRF24L01 radio module. Lastly, it provides an additional VCC and Ground pin, so that it can be easily powered externally.
This shield implements the MySensors recommended wiring connections: https://www.mysensors.org/build/connect_radio Therefore, MySensors software will "just work" without modification.
The LED's are optional. If preferred, you may add one or more of the LED's at a later time.
