How to externally power an eLite Jr MCU
If you have some minor soldering skills, its easy to externally power your eLite Jr or eLite Jr Signature.
There’s a programming header slot of the end of one side of the MCU with 5 holes all in a row. The first and second holes from the outer end aren’t used for power, the center is ground (GND), the next one over is 3-5v positive (V+), and the last one isn’t used for power. See the attached photo for clarification.
Don't forget to take out the CR1225 battery!!
