FireBeetle ESP32-E IoT Microcontroller (Wi-Fi / Bluetooth)
An ESP-WROOM-32E-basedĀ dual-core microcontroller boardĀ with lipo battery charging and ultra low power consumption, especially designed for IoT and perfect for wirelesslyĀ adding sensors to home automationĀ networks.
The new ESP32-E FireBeetleĀ supports WiFi and Bluetooth dual-mode communication, has ultra low power consumption and evenĀ includes an on-board charging circuit so you canĀ power it with aĀ lipo batteryĀ (and charge it over USB-C). It's easily programmable via Arduino IDE, andĀ idealĀ for smart home IoT, industrial IoT applications, wearable devices, and so on. You can easily create your own IoT smart home system when connecting it with an IoT platform like IFTTT or Home Assistant.
FireBeetle ESP32-E supports Arduino programming and will support Scratch graphical programming and MicroPython programming very soon, with detailed online tutorials and application cases. The castellated design makes itĀ possible to embed on another PCB, saving costs and time for building prototypes.
What's the difference between FireBeetle ESP32-E and FireBeetle ESP32?
- ESP32-E uses a data encryption chip to protect program security
- ESP32-E is equipped with a DFRobot GDI (General Display Interface) to connect screens like DFR0664/DFR0649/DFR0665/DFR0669
- Software are ecologically compatible with both ESP32 and ESP32-E, except for minor changes in pin mapping
- ESP32-E cannot use an expansion board for ESP32 V4.0

Espressif has recently released one wafer-level change on ESP32 Series of products: ESP32-E. Below are the main design changes in ESP32-E Series of chips:
- PSRAM Cache Bug Fix: Fixed āWhen the CPU accesses the external SRAM in a certain sequence, read & write errors can occurā.
- Fixed āWhen each CPU reads certain different address spaces simultaneously, a read error can occur.ā
- Optimized 32.768 KHz crystal oscillator stability, the issue was reported by client that there is a low probability that under ESP32-D hardware, the 32.768 KHz crystal oscillator couldnāt start properly.
- Fixed Fault injection issues regarding secure boot and flash encryption are fixed.
- Improvement: Changed the minimum baud rate supported by the CAN module from 25 kHz to 12.5 kHz.
