We now offer the NodeMCU, (version 2!) a development kit with open source firmware which will allow you to test your Internet of Things devices with minimal effort. The open-source, Wi-Fi enabled kit might be exactly what you need for your upcoming projects or perhaps it's just a useful tool to have in the workshop. Either way, check out the more in-depth feature list below.
