# Waveshare RP2040-Plus
|
||||||
|
|
||||||
|
The Waveshare RP2040-Plus Board is based on the Raspberry Pi RP2040 and can be
|
||||||
|
purchased with 4/16 MiB of flash.
|
||||||
|
|
||||||
|
These boards are available from a number of resellers
|
||||||
|
Waveshare maintain the [Wiki:RP2040-Plus](https://www.waveshare.com/wiki/RP2040-Plus)
|
||||||
|
Wiki containing information on the board.
|
||||||
|
|
||||||
|
## Build notes
|
||||||
|
|
||||||
|
Builds can be configured with the `BOARD_VARIANT` parameter. Valid variants
|
||||||
|
can be displayed with the `query-variant` target. An example:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
> cd ports/rp2
|
||||||
|
> make BOARD=WAVESHARE_RP2040_PLUS query-variants
|
||||||
|
VARIANTS: flash_4mb flash_16mb
|
||||||
|
> make BOARD=WAVESHARE_RP2040_PLUS BOARD_VARIANT=flash_16mb submodules all # Build the 16 MiB variant
|
||||||
|
```
|
||||||
|
|
||||||
|
`flash_4mb` is the default if `BOARD_VARIANT` is not supplied.
