Power-Up PCBA #2 October: SAMD21 ICs for Just $1.50 with Seeed Fusion PCB Assembly

October’s PCBA power-up has come early in the form of massive discounts on the ATSAMD21G18A, a member of the SAMD21 family of Arduino programmable, low-power microcontrollers as part of our campaign to improve our turnkey PCB Assembly offerings.

Almost a decade ago, Seeed Fusion introduced the PCBA Open Parts Libraries and since then, it has been serving the PCBA community with heapings of convenience and cost savings. More recently, Seeed Fusion hit a milestone, increasing the catalog from several thousand to over 150,000 different parts, boosting accessibility and enabling thousands of users to take advantage of lower costs and accelerated turnkey PCBA.

Then, with the positive reception and uptake of the Seeeduino XIAO, based on the ATSAMD21G18A, Seeed released the Seeeduino XIAO Hardware Development Kit (HDK). This has enabled developers to accelerate development with SAMD21 and since then several crowdfunding campaigns and products have been announced.

Enabling hardware development is part of Seeed’s ethos and bloodline. So now, we are going further and combining the two:

Please welcome ATSAMD21G18A-MU to the Seeed Open Parts Library.

And to celebrate the new addition, we are offering the SAMD12 chip at the special price of $1.50 USD, regardless of the number of units.

Based on one part per PCBA. Until further notice.

What does that mean? As with all PCBA OPL parts, these parts are available locally, often at much lower prices, so there is no waiting around for these parts to be imported. Furthermore, as a Seeed OPL part, Seeed maintains the stock and purchases in bulk, which means savings can be passed onto customers, hence the special price.

Accelerate your PCBA journey with the Seeed Fusion turnkey PCB Assembly service. Get an online quotation in minutes with the smart platform here and add extra services such as functional testing for complete peace of mind.

Add the ATSAMD21 chip to your Bill of Materials (BOM) by either including the full MPN in your Seeed BOM, or the Seeed SKU directly. The smart quotation platform will automatically read this from the OPL and show the discounted price and faster procurement time. More part details below.

You can use either the full manufacturer part number or Seeed SKU in the BOM
