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 interfacesIncluding 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.Board Overview of FireBeetle 2 ESP32-E (N16R2) Development BoardDual power supply modesSupporting 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 methodsIncluding Arduino IDE, ESP-IDF, Micro-Python, etc., catering to different developers' programming habits.Compact design, convenient for embeddingWith 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-32UETheESP32-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.Features: Equipped with ESP32-WROOM-32E-N16R2 dual-core module Clock frequency up to 240MHz, with 16M Flash and 2M PSRAM for large memory capacity Low-power development board, supporting dual-mode communication of WiFi and Bluetooth Onboard GDI display interface for quick connection to display screens Onboard charging circuit and PH2.0 lithium battery interface, supporting dual power supply and automatic switching Supports various programming methods such as Arduino IDE, ESP-IDF, Micro-Python Compact design, small size, suitable for space-limited and embedded IoT projects Applications: Home automation renovation Remote control of robots Environmental data monitoring Smart lighting control Control panel UI design Specification: Power Parameters Input Voltage USB-C interface: 5V DC PH2.0 interface: 3.7V Li-ion VCC pin: 5V DC MCU Parameters Processor: Tensilica LX6 dual-core processor (one core for high-speed connectivity, one core for independent application development) Clock Frequency: 240MHz SRAM: 520KB ROM: 448KB Flash: 16MB PSRAM: 2MB On-chip Clock: 40MHz crystal oscillator, 32.768KHz crystal oscillator Wireless Parameters Wi-Fi Standard: FCC/CE/TELEC/KCC Wi-Fi Protocol: 802.11 b/g/n/d/e/i/k/r (802.11n, up to 150 Mbps), A-MPDU and A-MSDU aggregation, supports 0.4us protection interval Wi-Fi Frequency Range: 2.4~2.5 GHz Bluetooth Protocol: Compliant with Bluetooth V4.2 BR/EDR and BLE standards Bluetooth Audio: CVSD and SBC audio Bluetooth Frequency Range: 2.4~2.5GHz Peripheral Parameters Digital Pins × 17: IO0, IO1, IO2, IO3, IO4, IO12, IO13, IO14, IO15, IO17, IO18, IO19, IO21, IO22, IO23, IO25, IO26 Analog Pins × 11: IO0, IO2, IO4, IO12, IO13, IO14, IO15, IO25, IO26, I34, I35 UART Interfaces: ×3 SPI Interface: ×1 I2C Interface: ×1 I2S Interface: ×1 DAC Interface: ×2 Touch Interfaces: ×7 LED PWM Channels: ×16 RGB_LED: WS2812 Display Interface: GDI Other Parameters Interface Compatibility: FireBeetle V2 series compatible Module Size: 25.4mm × 60mm Weight: 23.4g Documents: Product wiki Pinout Dimension Getting Started (Use for the first time) Arduino Tutorials Datasheet Schematic 2D File STP File Shell stl file Product Includes: FireBeetle 2 ESP32-E (N16R2) IoT Microcontroller x1 18pin-2.54mm Pitch Pin x1 18pin-2.54mm Pitch Pin Female x1 14pin-2.54mm Pitch Pin x1 14pin-2.54mm Pitch Pin Female x1
