Balloon Mission Computer 4 – update

I’ve got the PCBs and started assembling the components. had a few setbacks: I lost my GPS antenna, and damaged the camera during tests. so I’ve purchased the missing part and so far thing are looking good.

My biggest concern was will the raspberry pi’s power supply handle all the peripherals. I got the DORJI working in no time, but only in 0.5W. 1W is too much and causes restarts, but the low power is more than enough.

the GPS module was a pain to solder, but after a lot of effort, it’s working in i2c mode., and all is powered by a pair of AA batteries !

Still got lot’s of software to write & debug, but I think we’ll be ready to launch soon, so stay tuned…
