Hi all,
Long story short. I built a battery pack, bought 6 modules, one of the modules is a dud.
Looking to buy 2-3 modules (so I have spares) on their own.
If anyone has some at a reasonable price, let me know 
Thanks.
I vave about 10 4.4 modules that never were completed, can’t vouch for the attiny chips but a few are still untouched.
