  - M5Stack Timer Camera X<br />
 
 But it can probably run on many more.<br />

+The currently stable supported MCU's are: <code>ESP32</code>, <code>ESP32-S2</code>, <code>ESP32-S3</code>, <code>RP2040</code>, <code>nRF52840</code>.<br />
+The currently unstable supported MCU's are: <code>ESP32-C3</code>.<br />
+The currently unsupported CircuitPython-compatible MCU families are: <code>SAMD21</code>, <code>SAMD51</code>, <code>litex</code>, <code>mimxrt10xx</code>, <code>efr32</code>, <code>stm</code>, <code>unix</code>.<br />
+These MCU's are unsupported because I either can't get my hands on a decent board with them or they don't have enough ram for ljinux.<br />
+<br />
 The only real limiting factor should be ram, as about 70k (usable under circuitpython) are needed.<br />
