What is it?

ESP32-S3-MINI-1-N4-R2 (Dual core, 4M flash, 2M SPI RAM)
Genuine Waveshare 7.5" e-paper, 800x480 mono, laminated glass, black border, panel
24 WS2812 LEDs around edge, plus 1 by SD slot
Micro SD card slot
USB-C (2 alternate positions) for power / serial / programming
WAGO 2 pin for external power 5V-35V
WAGO 2 pin for contact switch (e.g. door bell)
Button-fix wall mount

Works with ESPhome, etc, can make weather station, general display, clock, etc.

No leads supplied.

Why did you make it?

My front door - interactive doorbell
Local Indian has one as a clock
Local pub has one as a clock and WiFi QR, etc.

What makes it special?

The normal 7.5" panel has an exposed panel border, but this model is laminated to a glass front with a black border - it makes for an excellent clean finish.

The controller is fitted to the back of the panel and has a button fix wall mount, meaning it can be mounted without a case, and the border LEDs reflecting off the wall.

Doorbell?

This is not designed to be waterproof, it is a development board, but suitable acrylic spray on the back should suffice in most cases (as on my own front door).

A thing of beauty!

The design of this board is so elegant that it should be on display itself!!

Extremely good support from the maker, and super-fast delivery.

The maker has clearly labelled all the GPIOs making it a breeze to understand. Seriously, this board has it all! USB x 2, inputs and outputs (including relay drive), dedicated power input - all with wago connectors, LEDs x 24, SD card and of course, an e-paper interface. I look at as a sort of ‘swiss-army’ knife board built for an ESP32.

The stock firmware has some very useful features such as WiFi QR code generation, image display, SNMP uptime, clocks (including TTG), and what day different bins go out. As a bonus, if you use ESPhome, then anything is possible.

What am I using it for? Currently I have one driving a Waveshare 7.5” e-paper screen, which the maker pairs in this bundle - a lovely Waveshare laminated black edge variant screen – simply the best; this displaying live data feeds from both a personal weather station and air source heat pump via ESPhome and MQTT, and another telling me what day the bins go out, sunrise, time and a constantly updated image of interest.

The possibilities are endless…..a fantastic board!
