2. When the key A is pressed, the first horizontal row on the top will light up.

3. When the key B is pressed, a vertical row near the key B lights

RP2040:bit Board Pins

The RP2040:bit Board has 25 external connections on the edge connector of the board, which are referred to as ‘pins’. The edge connector is the gold area on the right side of board as shown the figure below.

Pin	Description
0	KEYA
1	KEYB
10	GPIO that is conventionally used for the serial clock (SCK) signal of the 3-wire Serial Peripheral Interface (SPI) bus.
11	GPIO that is conventionally used for the Master Out Slave In (MOSI) signal of the SPI bus.
12	GPIO that is conventionally used for the Master In Slave Out (MISO) signal of the SPI bus.
13	CSn
17	These pins are wired to the 3V supply, like the large ‘3V’ pad.
18,19	Implement the clock signal (SCL) and data line (SDA) of the I2C bus communication protocol. With I2C, several devices can be connected on the same bus and send/read messages to and from the CPU. Internally, the accelerometer and the compass are connected to i2c.
29	ADC3
