Product Details

Hamamatsu C12666MA MEMS u-Spectrometer
Mfr. Part #
Product Description

This group buy is for a Hamamatsu C12666MA Micro-spectrometer. Its spectral response lies mostly in the visible range, 340 to 780 nm, with 15 nm of resolution. Its fingertip size of 20.1 × 12.5 × 10.1 mm and light weight of 5g make it very interesting to integrate into small embedded systems with a need to detect color.

Stay up to date on the progress of the breakout board for this product here, we will be carrying that product as soon as it is complete.


And whether you are fan of this part or not, you must check it out in action in Peter Jansen's "Open Source Science Tricorder" project here

If you are a forward-thinking producer or distributor of innovative products looking to nurture and leverage GroupGets' talented community of open-source developers and micro-buyers, contact us.

Why GroupGet?

If you are looking to add electronic color detection in a small footprint to your projects, this component is definitely worth a prototype. It's also over $50 cheaper than buying in single quantities. Pure Engineering is just about done with a custom breakout board for this and as soon as it's ready we will carry it here as an optional add-on and standalone at There will also be a new google group and github repo with sample code for this sensor (like with our Lepton GroupGet). Due to long factory lead times for the part, we are doing batches of 10 with limited timeframes. As soon as we get 10 orders they will go directly to Hamamatsu and a new batch will open.

How it works

This is a group buy campaign that needs to acquire at least the stated minimum amount of pledges from backers like you before the Unit Deliverable and any Add-Ons ship. We do not charge anyone until the Progress above hits 100% or greater, otherwise there is no charge. All campaign products are vetted as existing and functional so your order will be fulfilled within the Factory Lead Time if the campaign succeeds.
