FireBeetle ESP32 IOT Microcontroller (Supports Wi-Fi & Bluetooth)

by DFRobot

FireBeetle is a low-power consumption micro-controller intentionally designed for Internet of Things (IoT) projects.

The FireBeetle Board - ESP32 integrates a Dual-Core ESP-WROOM-32 module, which supports MCU and Wi-Fi & Bluetooth dual-mode communication. The electric current is just 10μA in deep-sleep mode. The main controller supports two power supply methods: USB and 3.7V external lithium battery. And both USB and external DC can charge the Lipo battery directly.

FireBeetle Board-ESP32 has made a special hardware design for Arduino IDE. You can make a download without switching booth-mode manually. It supports Arduino, IDF (linux), micropython etc. Moreover, FireBeetle has pin mapping for Arduino IDE. It can be configured with Dx transport, compatible with UNO and reduce the entry barrier.

The small size and high performance makes FireBeetle the ideal solution for IOT low power consumption projects.

Please kindly note that developers are the most common users of FireBeetle Board-ESP32 and not all of the peripherals have examples for reference, and there are still some bugs being found and fixed. For Arduino IDE, all GPIO function, I2C/SPI communication has been working. But the other functions are still under development. We recommend this board for experienced engineer.

Using ESP32 linked to a PC via a coms port and using the Processing freeware - and writing code to enhance the pixilation by factor of x10 - greyscale images Cap-0 and Cap-1 are produced. Opening in paint.net and applying a Gaussian filter yields Cap-0A and Cap-B. These are first steps - hoping to increase the "resolution" still further.

I couldn't get any of the referenced code to work without framebuffer errors and segmentation faults. After a good 12 hours of trying on a pi3 and pi4 I came across this GitHub page. Installing everything as sudo for python3 worked a charm. Pity Pimoroni don't supply such good code. Here it is: https://github.com/EverythingSmartHome/mlx90640-thermal-camera

Excellent bit of kit for the price. Easy to hook up and identify either using the software instructions on the page, or via other routes like I did - no issues at all getting it to pick up. The two sets of headers included is appreciated and made hooking up even easier.

Very speedy delivery - well done Pimoroni. The IR camera works well - I have used a Pi Zero to read I2C data from the camera and Display HAT Mini to render images. The project is a simple IR camera to help find thermal leaks from our house.

Best thermal camera that I could find in this price range with 32 x 24 pixels (the next closest is 8 x 8 pixels). I used mine to make a ghost busters ecto goggle headset - https://www.youtube.com/watch?v=bm6IWaHA0K4

Nice breakout but use with care! I wish the dead pixels were less prevalent, is this from the sensor itself or from the board implementation? We have between 2 and 3 dead pixels on the three boards we received.
