I’m pleased to announce that the production batch of SenseTemp and SenseTemp TEC boards have arrived from our assembly house. First article inspection and testing has started, and so far no issues have been found.

Functional changes from the prototype design include:

• SenseTemp & SenseTemp TEC: Changed from 0.1% to 0.05% rated reference resistors to improve the accuracy of temperature reading.
• SenseTemp: Support for operating from Li-Poly batteries connected to the Host Feather.
• SenseTemp TEC: Support for operating from just the 12 V DC power input by feeding regulated 5 V to the Host Feather (instead of it receiving 5 V via USB).
• SenseTemp TEC: Control of 12 V fan on the TEC header.

Every SenseTemp and SenseTemp TEC will be tested over the next few weeks, before shipping out in April.

To do that, we produced a small fixture that allows connection between SenseTemp and a host Feather via pogo-pins. This allows functional testing of the boards without soldering to them, which will enable you to assemble your SenseTemp and Host as you see fit.

Thanks for your support of this product. We look forward to getting SenseTemp to all of you!
