Dual power supply modes

Supporting both USB and external 3.7V lithium battery power supply, it can automatically switch between power sources under dual power supply, and supports both USB and external DC charging modes.

Support for multiple programming methods

Including Arduino IDE, ESP-IDF, Micro-Python, etc., catering to different developers' programming habits.

Support Arduino IDE, ESP-IDF, Micro-Python

Compact design, convenient for embedding

With a size of only 25.4mm × 60mm, onboard WiFi and Bluetooth antennas, and using stamp hole design, it is convenient to embed or integrate into PCB prototypes.

The difference between ESP32-WROOM-32E and ESP32-WROOM-32UE

The ESP32-WROOM-32E (this product) uses an onboard PCB antenna. This type of antenna is realized through PCB technology, does not require separate antenna assembly, is not easily damaged by touch, and is convenient for whole machine assembly. Onboard antennas can save space, reduce costs, and because they can be carefully positioned on the board, they can provide signal integrity. However, their gain may be lower than that of external antennas.

The ESP32-WROOM-32UE, on the other hand, connects to an external antenna via a connector. External antennas can be installed on the outside of the device and include both omnidirectional and directional antenna types. The main advantage of external antennas is that they can provide higher gain, thereby enhancing the communication range of Bluetooth or WiFi.

Furthermore, this product is one of the low-power IoT development boards in the FireBeetle series. If it does not meet your requirements, you can refer to the FireBeetle Series Selection Guide to choose a more suitable model.
