Never sold one! Retiring this product but you can still get it buying one of my epaper displays in the Flea Market!
NEW PRODUCT: If you want to control parallel epapers with a single PCB and harness all the power of a robust Espressif S3 MCU then try epdiy V7
In order to drive most known SPI epapers, you need an SPI adapter, that has a circuit that helps the internal controller to boost the required high voltages. Good-Display and Waveshare have their own products like DESPI-CO3 and others. But that means you need to wire 8 cables from your board to this devices (SPI + busy + RST and 3.3V power) This HAT solves this cable mess enabling you to wire this with a board that is the smallest and most efficient power consumption of it's kind: Any tinypico board from Unexpected Maker It will work either with Tinypico ESP32 or Tiny S3 just make sure to select the right GPIOs when you build it.
On the top of that has an PCF8563 RTC chip that is connected using the default I2C ESP32 pins (21 SDA and 22 SCL) so you can make a small device like a clock gadget or just send it to sleep and wake up with the RTC Interrupt pin. All that without adding any external wire.
Because I always need to wire and solder that 8 cables in any epaper display created...got kind of tired about doing that. Why not to simplify the work and make it look more professional?
The small form factor and being aware of time.
It comes with:
When ESP32 goes to sleep releases epaper RST pin, which makes the epaper consume like 1 mA/hr, this is offering an optional resistor that could keep this IO high when ESP32 goes to deepsleep. CR1220 is just the RTC backup battery, so in case your LiPo depletes completely, your device will still keep the time. Keep in mind polarity when soldiering this! The round side is the GND, the rect crossed side is +3 V.
