I am writing to inform you about our newest product, Hornbill.
Explore M3 was about learning to program and use the ARM cortex M3 and using them in your products and projects.
If you're looking for a similar powerful micrcontroller with builtin Wi-Fi and Bluetooth, Hornbill ESP32 should be good option for you. The Hornbill ESP32 dev board is the one to start with.
It has a the certified ESP32 module, a LiPo charger and built in USB to Serial. During the campaign the board is available for a special price of $12 including free shipping worldwide.
Should this interest you, head over to the campaign with the link below. There are several other options as well.
Once again, thank you for supporting Explore M3 and help us bring more open hardware to you.
