Just wanted to let you guys know about my next project dubbed Teensy Express.
I have posted info on hackaday.io, though only one of the daughter cards is pictured atm https://hackaday.io/project/11717-teensy-express
The goal of this board is to create a solderless expansion board with easily swappable project boards. I chose the PCIe mini connection due to high pin count, availability and no need the have a male connection on the daughter boards. This will allow users to simply design them using a prepared .brd file. The only constraint being 1mm board thickness.
It'll make much more sense as soon as I render the motherboard image.
Any thoughts and comments are welcome.
The pictured board is just an exercise in what can be done with the daughter board size (this one being cca 6x4cm, maximum 6x5cm). There is 3mm space height on the bottom side, enough for many parts. This example includes 10DOF, ESP12, MicroSD slot, CAN-BUS transceiver, and an LTE/GPS module (with SIM). All able to work simultaneously with the Teensy.
4.2V and 3.3V is supplied to this daughter board via the motherboard, from a battery or external VDC up to 14V.
