#159 Big ESP32 Boards Review and Test

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
