DESCRIPTION

The FireBeetle 2 ESP32-E (N16R2) IoT development board equipped with 16M Flash and 2M PSRAM. It is designed to provide superior performance for applications such as the LVGL graphics library for interface design and interaction. Built on the foundation of Espressif's ESP32-WROOM-32E-N16R2 module, it boasts a 32-bit dual-core processor with a clock frequency of up to 240MHz. With support for WiFi and Bluetooth dual-mode communication, it is an ideal choice for IoT scenarios.

Abundant peripheral interfaces

Including 17 digital pins, 11 analog pins, 3 UART interfaces, 1 SPI interface, 1 I2C interface, 1 I2S interface, and 2 DAC interfaces, it can meet various hardware connection needs.

 

Support for multiple programming methods

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

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.

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.
