LWC Meshtastic "Meshformer" communicator Node

More pictures and info comming soon……hopefully. 

The ready assembled FakeTec board gets attached to the back of the Card KB keyboard with double sided sticky tape ( the 1mm thick foamy one)  make sure the USB C port aligns with the opening on the bottom. 

The magnetic pogo pin connectors  need to be attached  with some epoxy on both port  sites,  make sue the mounted display+magnetic connector are facing the correct way and do have contact to each other! Once the epoxy is hardened and you find out they dont make proper contact its too late! 

Connect both  magnetic ports to the FakeTec Display outlet, simply connect them all in parallel ( also the Card KB I2C keyboard!) 

The main power switch slider needs to be shortened, so simply use some side cutters for that.

Glue the main power switch in place with superglue.

The battery should fit in snug but you can use some double sided tape if you experience movement of it when closed up.

The card kb Keyboard closes up the case with everything in place, use 4 screws in each corner to hold it in place. 

Attach the cable cover over the exposed Atmel chip and wires and secure it with two screws on the side. 

The swappable display needs to be connected to the magnetic pogo pin connector, if you place it reasonable you can reach the 2 outer contact point and leave the middle one untouched so you can provide it with +/- and SLC and SDA, be careful when solder the screen to the connector so it is parallel  and also dont heat the pins for to long, you dont want to melt them out of the frame.

Once the pogo pin connector is soldered to the I2C oled display, slide them in the display frame and close it up on top with the lid, use some glue ( carefull with superglue as it leaves white spots if you use to much of it!  You dont want that on the front of the display.
