Over the last few month, a lot of new ESP32 boards appeared on our usual marketplaces. It is time for a closer look. That you can save your money and buy the board you really need.
Here I have most of the current “made in Asia” boards and I will give you an overview of their features and functions:
• Number of pins available for the user
• ESP32 Module and ESP32 chip revision used for the board
• Is the board breadboard-friendly?
• Does it have special features like OLED or a LiPo battery charging circuit?
• Does it have a flash button, and a USB connector?
• I will measure the current for the different
- idle
- Bluetooth active
- Wi-Fi active in STA, AP, and both modes
- Wifi and Bluetooth active
- Deep Sleep
• I will also measure the current during charging for the boards with a battery
• And I will comment positive and negative features and experiences with these boards
