+## Powering Motor 2040
+Motor 2040 can be powered either by plugging the board into a USB-C power source (like a PC or power adapter) or by connecting a battery pack to the EXT PWR or VSYS connections. On an unmodified board, **you should only have one power source connected at a time**, to avoid back-powering your computer or battery.
+
+If you want to have two power sources connected at the same time, Motor 2040 has two traces on its underside that you can cut to do this safely.
+
+- **Cut EXT PWR to VSYS** if you want to provide your motors with a separate power supply (up to 10V) from that used to power the rest of the board. Board power (up to 13.2V) will need to be provided either by USB 5V or VSYS.
+- **Cut USB 5V to VSYS** if you want to run the board entirely off a separate power supply, without worry of back-powering your computer. Note that this also means the board will not turn on when only connected by USB.
+
+## Notes
+- \* The current limit of each motor can be disabled by soldering the "high current" pads on the rear (doing this will also disable the current monitoring). The maximum supported output current is 1.2 A continuous (2 A peak) per motor.
+- ** The direction indicators for each motor can be disabled by cutting the "motor LED" traces on the rear.
+- The pinout of the JST-SH motor connectors is M+, M-, 3v3, A, B, GND.
 
 ## About RP2040
 Raspberry Pi's RP2040 microcontroller is a dual core ARM Cortex M0+ running at up to 133Mhz. It bundles in 264kB of SRAM, 30 multifunction GPIO pins (including a four channel 12-bit ADC), a heap of standard peripherals (I2C, SPI, UART, PWM, clocks, etc), and USB support.
