+ | === Power === | ||
+ | |||
+ | This device can be powered by either the pins on the serial port or via the DC input jack. In either case the MCU can be provided with 3V3 or 5V. The jack feeds two LDO regulators which may be set via a jumper to select the required voltage. | ||
+ | |||
+ | The kit comes with a 16M resonator but I have installed a 16 MHz XTAL. The MCU is not rated to run at 16M using 3V3 but this configuration works fine for me. | ||
