Schematic design feedback

@oraclerouter ,

I think you have hit on the main point with temperature control for your charging.

Take a look at this thread for some ideas on how best to handle this. My approach was to put a temperature sensor on my carrier board and determine whether to charge each hour. You will also see some great suggestions on improvements too.

Safe Charging for LiPO batteries - deviceOS@2.x LTS Approach

First, let me start by saying that I am very happy about Particle’s decision to pursue a long term support approach to deviceOS. If you want to read more, please see @vikram’s excellent post here: For devices in remote locations, like mine, having a focus on stability and reliability is a much apprecaited improvement. I plan to use the LTS approach for my devices as much as possible. I am starting this thread as a continuation of this one given the move from 2nd Generation to 3rd Generation…

I think you approach with the switch is very simple and effective. By limiting the charge current via the pmic commands or the new serPowerConfiguration API, you should be all set.

Thanks,

Chip
