I bought one of these to develop software for Sonoff relays (given they share the main architecture). It works very well and it is very convenient as it has a micro USB connection. The packaging was adequate with plenty of foam protecting the unit, though maybe a little foam on the pins might help too as in my package they had punched through the ESD packaging. Still, no harm was done and it works flawlessly. Recommended

I ordered this module for a project of mine, and it works flawlessly. It can be simply programmed with the free Arduino IDE through it’s MicroUSB interface. The package was good, the foam ensured that the board doesn’t get damaged. Highly recommend this module.
