ssis.bit
AIO solution for SSIS students
Hardware
CircuitPython supports more than 200 different boards. Locally available is the TTGO T8 ESP32-S2 ST7789 at several online stores. The board includes the powerful 240MHz CPU, 4MB Flash and 8MB PSRAM, a 1.14″ ST7789 display, a microSD card slot for virtually unlimited local data storage, battery connector 1.25mm JST with charge controller and regular USB-C connector. And buildin WiFi, of course.
The planned adapterplate adds a 3-way button for input, place to hold the little 350 mAh battery and interface for I2C with regular 2.54mm 4pin JST XH as well as the small Stemma QT 1mm JST SH connector (QWIIC).
Software
The ssis:bit runs CircuitPython and can be easily programmed with the Mu Editor. There is a lot to learn on Adafruit with CircuitPython and with their great libraries there is less frustration getting things started.
History
More will be updated in the docs/history document, but the idea is from 2020 with the t-display board. Similar idea: Not just the Microcomputer but included power supply (LiPo), display (just 240×135 color) and input device (not keyboard, but 3 buttons) to have it always with you and ready to use.
