The Thingy:52 (PCA20020) is a prototyping platform build around the nRF52832 from Nordic.

Peripheral Support

Peripheral	Support	NOTES
UART	Yes
Buttons	No
LEDs	Yes	Lightwell RGB LED (SX1509)
NFC	No
IMU (MPU-9250)	No
Low power accelerometer (LIS2DH12)	No
Pressure and temperature (LPS22HB)	Yes	uORB, sensor_baro0
Humidity and temperature (HTS221)	Yes	uORB, sensor_humi0, sensor_ambient_temp0
Color sensor (BH1745NUC)	Yes	uORB, sensor_rgb0
Gas sensor (CCS811)	Yes	uORB, sensor_co20, sensor_tvoc0
Microphone (MP34DB02)	No
Speaker	No
Battery monitoring	Yes	SAADC AIN4 (P0.28)

Serial Console

At default serial console is available with Segger RTT driver. For access to the RTT console use this commands:

JLinkGDBServer -if SWD -device stm32h743zi -speed 16000
sudo socat -d -d PTY,link=/dev/ttyRTT0,raw,ignoreeof TCP:127.0.0.1:19021,reuseaddr
minicom -D /dev/ttyRTT0

An alternative option is to use the P4 connector and connect an external UART converter:

Pin	Signal	Notes
P0.02	UART0 TX	P4 header
P0.03	UART0 RX	P4 header

For this you need to select the following options in your configuration:

CONFIG_NRF52_UART0=y
CONFIG_UART0_SERIAL_CONSOLE=y

Configurations

Each configuration is maintained in a sub-directory and can be selected as follow:

tools/configure.sh thingy52:<subdir>

Where <subdir> is one of the following:

nsh

Basic NuttShell configuration (console enabled on Segger RTT channel).

thingy_nimble

NuttShell configuration with the nimBLE host stack, the SX1509 IO expander and LED driver, the buttons and GPIO examples and the on-board uORB sensors (HTS221, LPS22HB, BH1745NUC and CCS811) enabled.

Flash & Debug

Both flashing and debuing is possible only with an external debug probe.
