PCB CL BT V1.0.JPG
Now PCB Routing.

Edit 08/03/21:
Send PCB files for production.

Edit 20/04/21:
PCB assembled and tested.
All Works, just need to change the voltage regulator by another with dropout lower (1117-3.3 is +/- 0.8-0.9V, is to hight for battery, Bat @4.1V LDO out 3.2V). Move left switch (Too close to the antenna).
I need to check if the IC charger, empty the battery if there is no voltage on the microUSB.

Dear Olivier
That looks fantastic... Who would have believed that a 35 year old hand held computer could be equipped with blue tooth communications... You should be very proud.

Is the rechargeable battery charged in-situ or does it need to be removed?
Do I see three 'switches' ?? Blue tooth pairing ?? on/off switch ?? 'other' ??
I can't wait to see it working; I bet Νίκος is beside himself.

Sincerely... Martin

Hello All,

I made good progress on the box:
Case_Front.jpg
Add 1 or 2 mm to hide the small space.
Case Back.jpg
Correction of the PCB, the box is slightly offset.
Case Down.jpg
Small corrections to be made.
I still have to check if the connector contacts are good.
