The Raspberry Pi Pico WH is the Pico W version with pre-soldered headers. There are two major differences between Pico and Pico H versions. The rest of the features are the same on the Raspberry Pi Pico W and WH.
Difference between Raspberry Pi Pico W and Pico WH
- Raspberry Pi Pico WH has pre-soldered headers.
- Whereas the Raspberry Pi Pico W is a castellated module which allows the user to solder directly to the carrier board.
Keyed 3-Pin Connector
- The Serial Wire Debug (SWD) 3-Pin header on the Pico WH is broken out into a small Keyed 3-Pin connector.
- The Serial Wire Debug (SWD) header on the Pico W has 3 through-hole castellated pins.
Raspberry Pi Pico WH is a member of the Raspberry Pi Pico series with the Single-Band 2.4GHz 802.11n add-on wireless interface. The form factor of the Pico remains the same. The Pico WH features the CYW43439 Infineon chip.

- Temperature sensor, dormant mode, low-power sleep mode, and Drag & Drop programming through storage USB
- On-chip accelerated integer and floating-point libraries
- Some wireless interface pins are shred because of the pin limitations. VSYS monitor and CLK are shared and this is why the ADC can read VSYS only where not SPI transaction is in progress.
- The same pin on the RP2040 is shared by IRQ and CYW43439 DIN/DOUT. This means that IRQs can be checked when there is no SPI transaction in progress.
- For optimal wireless performance, make sure that there is no metal near or under the antenna. You can improve the bandwidth by adding grounded metal to the sides of the antenna.
