Description

FireBeetle 2 ESP32-E is a main controller board based on the ESP-WROOM-32E chip, specifically designed for IoT applications. It features dual-core chips and supports WiFi and Bluetooth dual-mode communication. It is small, ultra-low power, has an onboard charging circuit, and an easy-to-use interface, making it suitable for use in smart home IoT, industrial IoT, wearable devices, and more. With the ability to connect to an IoT platform like IFTTT, it is easy to create your own smart home system.

FireBeetle 2 ESP32-E supports Arduino programming, and will soon support Scratch graphical programming and MicroPython programming. Detailed online tutorials and application cases are provided, along with access to thousands of sensors and actuators with welding-free Gravity interfaces to help you get started easily. Its stamp hole design allows for easy embedding in your PCB, saving time and costs in building and testing prototypes.

Board Overview

Pinout

Espressif has recently released one wafer-level change on ESP32 Series of products (ECO V3). Below are the main design changes in ECO V3 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 ECO V1 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.
