Pimoroni Tiny 2040 (RP2040)

The Pimoroni Tiny 2040 is a Raspberry Pi RP2040 evaluation board. As the name suggests, it is particularly small (~ 22.9 x 18.2 x 6mm (L x W x H, including the USB-C port)).

Features (selection)

  • RP2040 MCU
  • 8MB on board QSPI flash
  • USB-C
  • On board RGB-LED
  • 12 I/O pins
  • external debug connector pads

For further information please refer to the Pimoroni Tiny 2040 web page.

Setting up with J-Link

Debug interface connection

The Pimoroni Tiny 2040 evaluation board comes with an external SWD debug connector (3 pins: SWCLK, GND, SWDIO). To set the board up with J-Link, the following steps are required:

  1. Solder a 3-pin pin strip to the debug connector pads.
  2. Solder a pin Strip to the GPIO pads of the evaluation board. The relevant pad is Pad 3 3V3 (3V)

  3. Connect the J-Link to the evaluation board, using jumper wires as follows:

    Pin Tiny 2040 Pin J-Link Signal
    "DEBUG" "SWC" 9 SWCLK
    "DEBUG" " - " 4 GND
    "DEBUG" "SWD" 7 SWDIO
    "3V" Pad 3 1 VTref

Note: For a more reliable, simpler solution, the SEGGER Flying Wire Adapter is recommended.
