New Cinwrite SPI HAT for IT8951 parallel epaper controllers

At the moment only available in Tindie Fasani Corporation store this PCB mission is to provide:

  • ESP32S3 Espressif MCU with 2MB of external RAM
  • WiFi
  • BLE
  • DS3231 real time clock and small CR1220 coin battery to keep time
  • Fast 40Mhz SPI
  • 3V to 5V step-up (And a way to enable this boost converter)
  • 3.7v LiPo battery charger

This Cinwrite PCB is open source Hardware that you can explore and even adapt to your needs.

The price is 45 USD since I only made 5 and otherwise it will be impossible to cover the costs. But it might go lower if we can make a budget version without Bluetooth, that is, provided there is some interested parties in using it.
This along with DEXA-C097 IT8951 controller sold by GoodDisplay, and fabricated by CINREAD, can be a very powerful option to use very fast 8-bit parallel displays, such as ED097OC4 or ED097TC2. There are many models available and all of them should work, they just have different contrast and VCOM voltage adjustments.
Making this board a very good option to control them and make a digital clock for a store, or add sensors in it’s dedicated I2C connector, such as Humidity, CO2 air quality or anything that can be plugged in this super fast MCU from Espressif.

Testing Pine64 Quartz model A board

The Quartz64 Model A is powered by a Rockchip RK3566 quad-core ARM Cortex A55 64-Bit Processor with a Mali G-52 GPU. It comes equipped with 2GB, 4GB or 8GB LPDDR4 system memory, and a 128Mb SPI boot flash. There is also an optional eMMC module (up to 128GB) and a microSD slot for booting.

So far I tried the following and worked out without issues:
– Installed Balena etcher in Ubuntu, a nice software to make bootable SD’s or eMMC
Downloaded last version of Manjaro-arm for this board (at this moment: 0220606 release)
– Connected an external monitor using HDMI, an external wireless logitech Keyboard/Mouse, all recognized automatically by Manjaro

Additionally I wrote a post in Pine64 forum, since I want to know how to go further and test the Eink interface.

This is the result:

Curious to connect a LAN cable afterwards since this does not have WiFi and also trying out a WLAN USB to see if I can also use external WiFi.
