Free prototype PCBs from Seeed

Seeed Studio is running a sponsorship campaign of the Seeed Fusion Assembly service offering free PCB prototypes for DIY keyboard projects with a XIAO RP2040 controller included.
Published May 23, 2022

Last year, Seeed Studio introduced XIAO RP2040 to the XIAO family.

As the name implies, it's an alternative controller with an RP2040 chip on board. Similarly to other development boards like the Pi Pico, KB2040, etc., it supports CircuitPython and KMK firmware – but in a smaller XIAO form factor (21 x 17.5mm).

A few weeks ago, after I featured MReavley's Slice36 with a XIAO RP2040 and also a Hummingbird with a XIAO BLE, I reached out to Seeed to see if there's any opportunity for cooperation.

As a first step, Amanda offered a bunch of coupon codes for you and kindly pointed me to this page.

Free PCBA prototyping

The point is, they are promoting their PCBA assembly service or "Seeed Fusion’s one-stop-shop capabilities": Get 2 boards fabricated and assembled completely free.

The point is, in order to stimulate enthusiasm and help customers to land more productive and valuable projects, Seeed are sponsoring Seeed XIAO RP2040 designs with the Seeed Fusion PCBA service:“Each person is limited to two PCBA boards 100% FREE for one design. The custom design must include Seeed XIAO RP2040.”

If you have an interesting concept for Seeed XIAO RP2040 custom design and are willing to share it with the community, share it with us and we can help you make it a reality with Seeed Fusion’s one-stop-shop capabilities. Get 2 boards fabricated and assembled completely free with Seeed Fusion’s turnkey PCB Assembly service.

Review the service

If you would like to participate in this Seeed XIAO RP2040 & Fusion PCBA campaign, Seeed Fusion hopes that you are willing to share your shopping experience, and allow them to share it and your project* with the community on their social media platforms. (*The design does not need to be open-sourced unless you want to).

If you'd appreciate some exposure: the Seeed Twitter, Facebook and LinkedIn accounts have 54k, 45K and 10K followers, respectively.

Act now and check out the details here. You have nothing to lose.
