I am starting this topic because it may be of interest to some of you having trouble getting your CHIP computers to run consistently.
During my explorations of Ferrite Isolators on SNR, I made some measurements of the charging voltage of the Boston Power battery connected to the CHIP. Using a setup as follows:
I discovered the optimum voltage on the BATTERY/GND pins on the CHIP was 3.6 vdc.(See the 2 wires coming over the gold label on the CHIP's CPU going to my volt meter). I found that some of my USB cords (4 ft to 10 ft) only provided 3.2 vdc at the same pins. Not enough even thou I'm using a 2.1 amp wall wart because of cable loss when loaded!!
Check your system and see what you get. Ken
