So now we have not one but two data ports how to present this in useable functional format, yet keep production costs down.
On one LED on a fly lead with heat shrink is 21 actions, half of them by robot or machine and half by human. With JST reduces it to 12.
Trade off is size. Up from 292 to 342 sq.mm to accommodate JSTs.
Now add in the connectors it’s up around 450 sq.mm. Full plug n play.
We will of course offer a simple chip with just power and motor wires and Carrera LED and Scorpius sensor all soldered, no plugs. Zero plug n play.
This is the latest design. The twin data ports allow two 12C based functions simultaneously, ie a tacho and an OLED screenof brushless motors wth OLED. Combine the two and you can now see your revs on the screen.
Plug n play is huge now. Unless it’s plug n play people will simply find the easy solution.
What’s also important is that the connectors are 100% Carrera compatible. The MPD deluxe is.
Carrera could have done it better but it is what it is but we did remove one wire pair and convert it to a surface mounted JST.
PT is the photo transistor ports. 2 of, as the Carrera Lane Brain will need 2.
And we grabbed the extra required headlight plug by soldering on the underside to get two lots of JSTs off one pair pins without twisting wires. This will save a few strips in production also.
Motor wires moved to centre rear.
Power wires centre front.
Scorpius surface mounted photo transistor removed.
Board length configured to match connector width.
So the basic chip is still small at 342sq mm.
And the deluxe one still 1/3 smaller than Carreras chip at 460 sq mm.
The factory doubled its price on hand soldering and this is the driving force behind this decision.
