README
README.mdbitaxe-ESP-OLED
bitaxe-ESP-OLED is a carrier board for a specific 1.9 inch 170x320 OLED which is intended to connect to a bitaxe device via the BAP (Bitaxe Accessory Port) The carrier board contains an ESP32-S3 MCU that drives the display and receives status info via UART using the BAP (Bitaxe Accessory Port)
Here is the OLED display
The display attaches to the front of the carrier board using double sided foam tape, and the connector wraps around through the notch and attaches to the 30-pin connector on the back.
This OLED display uses a ST7789 controller operates in parallel mode through its 30-pin connector.
The carrier board uses an ESP32-S3 MCU to drive the OLED.
On the side of the board there is a Reset button, a bootmode button, and two user buttons used for navigating the GUI.
The MCU firmware will display various GUI pages, and the data for these pages will be supplied by the bitaxe through the UART.

Questions
How big is the Bitaxe ESP OLED PCB?
It measures 56.6 × 41.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Bitaxe ESP OLED use?
58 parts, built around the ESP32-S3(R8V), AP2502KTR-G1, W25Q128JVSIQ and RT9080-33GJ5. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bitaxe ESP OLED KiCad files?
From the macphyter/bitaxe-ESP-OLED repository on GitHub, at the commit this page was made from: the board is bitaxe-ESP-OLED.kicad_pcb and its schematic bitaxe-ESP-OLED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bitaxe ESP OLED design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
