Hi Luke,

Thanks for your double check.
My new board is ready, i will send Gerber file to China quickly.
When I wil got pcb, after testing, errors (!) correction ... i will publish Eagle files.

Best regards,

PS : Sorry Luke, but after your explanations, I2c connector was sacrified !

Hello,

I'm  working on a new "piggy-back TCB" plugged on a standard ATMega board.
As said before I'm not very young and fitting a pcb with smd components smaller than 1206 size, is a pain for me.

I need to reduce the length because on the previous pcb, some pins connectors were in contact with USB plug on Mega board.
My new prototype board would use "big components", and because space available is not very wide, some functionalities will be sacrified.

I have seen that Luke add some possibilities for DIY boards, and I would like to clarify some details :

- Machine Gun mosfet drive was driven with PE2, non available on Mega board
   Now connected to PD1 (Pin 20  SDA of I2c port)   
   Correct ?

- Recoil switch was connected to PE6, non available on Mega board
  Now  connected to PD0 (Pin 21  SCL of I2c port) 
  Correct ?

So, I2c connector can be removed
L298 removed and replaced by 2 connectors for external drivers as like chinese Monster Moto shield
IR battle components removed and replaced with connector.
5V regulator is removed and Servos connectors, leds, and all accessories are powered by a BEC.

We can discuss about that, my Eagle files (and Gerber) would be available for everybody.

Have a nice day
