Description

The FireBeetle 2 ESP32-E is a main controller board designed specifically for use in the Internet of Things (IoT). It is based on the ESP-WROOM-32E and features dual-core chips. The board supports both WiFi and Bluetooth communication, and is notable for its small size, low power consumption, on-board charging circuit, and easy-to-use interface. These features make it well-suited for use in a wide range of IoT applications, including smart home systems, industrial IoT, and wearable devices.

In addition to supporting Arduino programming, the FireBeetle 2 ESP32-E will soon support Scratch graphical programming and MicroPython programming. Online tutorials and application cases are available to help users get started, and there are thousands of sensors and actuators with welding-free Gravity interfaces that can be easily connected to the board. The stamp hole design of the board also allows it to be easily embedded in a PCB, saving time and costs when building and testing prototypes.

Features
  • ESP32 Dual-core low power main controller, 10uA power consumption
  • WiFi+Bluetooth 4.0 Dual-mode Module
  • GDI Display Port, easy to connect
  • Onboard Charging Circuit and PH2.0 lithium Battery Interface

Board Overview

Pinout

Espressif has recently released one wafer-level change on the ESP32 Series of products: ESP32-E. Below are the main design changes in the ESP32-E Series of chips:
1. PSRAM Cache Bug Fix: Fixed “When the CPU accesses the external SRAM in a certain sequence, read & write errors can occur”.
2. Fixed “When each CPU reads certain different address spaces simultaneously, a read error can occur.”
3. Optimized 32.768 KHz crystal oscillator stability, the issue was reported by the client that there is a low probability that under ESP32-D hardware, the 32.768 kHz crystal oscillator couldn’t start properly.
4. Fixed Fault injection issues regarding secure boot and flash encryption are fixed.
5. Improvement: Changed the minimum baud rate supported by the CAN module from 25 kHz to 12.5 kHz.
