This section lists known issues and warnings for the Maple RET6 Edition.
+* **Power Supply Marketing Mistake**: We originally sold the Maple

* **UART4, UART5 GPIOs unavailable**: Pins related to the digital
to analog converter (DAC) and UARTs 4 and 5 are not broken out to
headers. The RET6 Edition's hardware layout is identical to that of
