UART is accessible on a standard connector but with unusual speed: 1500000
If you don’t have USB Type-C PSU, you can power the board via pins 4 (5V) and 6 (GND) of the 40-pin GPIO1 header
Powering related troubles are possible since USB Type-C is not PD-compliant

If you want to boot from your SD card you need to hold boot button while powering up/resetting

UART is accessible on pin 6 (GND),8 (TX) and 10 (RX) and with unusual speed: 1500000
Video and 3D acceleration addon
Clocking to maximum safe CPU speed (1.51Ghz) is possible this way:
```
sed -i "s/MAX_SPEED=.*/MAX_SPEED=1510000/" /etc/default/cpufrequtils 
service cpufrequtils restart
```
Make sure to install large heatsink!

Severe powering troubles due to Micro USB power connector. It’s recommended to power through GPIO pins to prevent under-voltage issues (instabilities, boot/crash cycles). Powering situation is a little improved/masked on model S.
serial console is enabled on UART2 (pin 32, 33, 34=gnd)
eMMC flashing (model Tinkerboard S with eMMC) can be done the same way as burning an SD card. Connect your board with USB cable to your computer (Linux or Windows) and eMMC will be seen as a new hard drive. Burn an image to this drive. Wait until it's done, detach from computer and power with your normal PSU.
booting from SD card on S model is possible in Maskrom mode.
