Serial Console
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
By default a serial console appears on pins 1 (TX GPIO0) and pin 2
|
|
|
|
|
(RX GPIO1). This console runs a 115200-8N1.
|
|
|
|
|
|
|
|
|
|
The board can be configured to use the USB connection as the serial console.
|
|
|
|
|
|
|
|
|
|
Buttons and LEDs
|
|
|
|
|
================
|
|
|
|
|
|
|
|
|
|
No user LED is provided.
|
|
|
|
|
|
|
|
|
|
A BOOT button, which if held down when pressing RESET or power is first
|
|
|
|
|
applied to the board, will cause the RP2040 to boot into programming
|
|
|
|
|
mode and appear as a storage device to a computer connected via USB.
|
|
|
|
|
Saving a .UF2 file to this device will replace the Flash ROM contents
|
|
|
|
|
on the RP2040.

Power Supply
|
|
|
|
|
============
|
|
|
|
|
|
|
|
|
|
The Raspberry Pi Pico can be powered via the USB connector, connecting
|
|
|
|
|
a lithium battery through connector, or by supplying +5V to pin 18(VSYS).
|
|
|
|
|
The board had a diode that prevents power from pin 18 from flowing back
|
|
|
|
|
to the USB socket. Power through USB or VSYS will be charging the battery
|
|
|
|
|
if connected. The schematic is available at `RP2040-LCD-1.28-sch.pdf <https://www.waveshare.net/w/upload/6/60/RP2040-LCD-1.28-sch.pdf>`_
