YD-ESP32 Original Espressif Module ESP32-WROOM-32E-N4/N8N16.The YD-ESP32 is fully compatible with Espressif’s official ESP32-DevKitM-1 and ESP32-DevKitC-1.The link core board uses the ESP32-WROOM-32E module recommended by Espressif in 2022 for the production of the newly designed ESP32-D0WD-V3 chip. Programs running on the deprecated models can be seamlessly run on the recommended chips or modules without modification, and the chips and modules recommended for new designs in 2022 (ESP32-D0WD-V3 and ESP32-WROOM-32E) are compared to the undescribed models, improving the chip production process, reducing power loss, improving signal quality, etc. These changes make the chip more stable, reliable and green low power consumption.The link core board is the ESP32-WROOM-32E module recommended by Espressif In 2022 for the new design. The module has 3 different external flash configurations, often said ESP32 can actually be used without external flash, because the ESP32 chip itself has a built-in 448KB ROM, which is enough for general applications of this 448KB ROM, but it involves some data that needs to be stored or needs to rely on external storage Flash, which can provide 4M, 8M, 16M external flash can be selected. Large external Flash capacity modules can be seamlessly compatible with small-capacity Flash module programs without modification.

ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC ultra-low-power 40 nm technology. It is designed to achieve the best power and RF performance, showing robustness, versatility and reliability in a wide variety of applications and power scenarios.
