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.
