https://stream.echo6.co/videos/watch/80e04a21-982d-4f85-964a-bfcdaf5fa48a 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 Board with 18650: http://bit.ly/2eZAp8j WeMos® LOLIN32 Board http://bit.ly/2t2zXeW TTGO Module: http://s.click.aliexpress.com/e/QbqFa6i ESP32 (NodeMCU type) Board: http://bit.ly/2eZ1s3u White OLED: http://s.click.aliexpress.com/e/6Eu7q3j Wemos OLED: http://bit.ly/2tosirM Yellow: http://s.click.aliexpress.com/e/RR7Em6U Geekit (similar to Yellow, not tested): http://bit.ly/2sOMR3E X-Board: http://bit.ly/2vXimql Mini board: https://www.aliexpress.com/item/MH-ET-LIVE-D1-mini-ESP32-ESP-32-WiFi-Bluetooth-Internet-of-Things-development-board-based/32816073234.html Arduino like Board: http://bit.ly/2tUZVnC ESP32 programmer: http://bit.ly/2vXsJue WROOM-32 Module: http://bit.ly/2vXQouD ESP32 PCB: http://s.click.aliexpress.com/e/jaqNzF6 Github: https://github.com/SensorsIot/ESP32-Board-Test Supporting Material and Blog Page: http://www.sensorsiot.org If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) Official Wemos Store: http://s.click.aliexpress.com/e/jUzBiIq https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa https://www.instructables.com/member/Andreas%20Spiess/ Please do not try to Email me or invite me on LinkedIn.
