Thanks
E***u –
Cannot get it to work with VESC. Larger model works
K***s –
These are differently sized than the other nrf51822 modules in the same form factor, but they’re still the QFAA chip and the pins are still 2.0mm instead of 2.54mm
I***y –
Very long delivery. A similar product, bought simultaneously with this came 3 weeks ago.
