The vent hole of the BME680 is at the bottom and the battery curves up a bit at this point, so the vent hole will likely not be covered, but I don't wont to guarantee that at the moment.
We should think about adding pads for an optional BME680 on the top PCB. We can put it on a different I2C address too.https://git.flow3r.garden/card10/hardware/-/issues/82Connect one of the TP pins to a GPIO2019-07-02T12:44:29ZschneiderConnect one of the TP pins to a GPIOWe are trying to get the TE (tearing effect) pin of the LCD controller connected to the one of the (otherwise unused) TP pins of the FPCB.

We have one pin left: PMIC_GPIO but that only goes to the PMIC and then via I2C to the controller. I'm not sure if that will be fast enough (maybe via the interrupt).
Proposed solution:
- Add 0 Ohm resistors to both TP pins (we don't know which one will be connected ATM)
- Connect the PMIC_GPIO after the 0 Ohms
- Connect a 1M resistor to one of the SAO GPIO pins after the 0 Ohmshttps://git.flow3r.garden/card10/hardware/-/issues/81Define panel design2019-07-02T19:44:34ZschneiderDefine panel designWe populate both sides until the edge. If the panel is large I fear it will bend a bit and needs support.
We might have to put a bit of space between the individual PCBs so the panel can be supported while going through the line.
