From the project

N1KDO Raspberry Pi Pico-W Dual Serial Interface.

This is a simple board that supports two RS-232 serial ports (TXD & RXD only) with a Raspberry PI Pico-W. This is useful to internet-enable devices that support a serial interface.

This board is sized for a Hammond Manufacturing 1591XXSFLBK enclosure.

Pico w dual serial: common questions

What microcontroller does the Pico w dual serial use?

The Pico w dual serial is built around the PicoW, from the RP2040/RP2350 family.

How big is the Pico w dual serial PCB?

The Pico w dual serial measures 86.4 × 76.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pico w dual serial?

59 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pico w dual serial design files?

From the n1kdo/pico-w-dual-serial repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pico w dual serial design in my own project?
