custom Arduino mega 2560 PCB

Move a working developed Adruino Mega project to standalone ATmega module.

1 additional integrated circuit + custom Header / Connectors for external sensors/modules,

Could also be done Via custom Expansion Shield + Mega2560-core Mini 2560 for example.

Custom Expansion Shield specs needed / ATmega module

Additional circuit :

max31856 EGT

1 x 2 pin plug


5 Pin header plug for existing prebuilt module

1 x 2 pin power

9v ..14v vehicle power

Fused, reverse pol protected, 5v 2A

1 x 3 Pin

Serial Comms output

1 x 5 pin plug

Rotary encoder/switch

4 x 3 pin plugs

5v Pressure sensors input

4 x 3 pin plugs

Temp sensors

DS18B20 based sensors network so will have 4.7K resistor signal-5v on board on single anolg input

1 x 3 pin plug


ground, 5v, analog input signal

1 x 4 pin header

on board Knock sensor module (5cm x 5cm)

ground, 5v, analog input signal, digital input signal

1 x 2 pin plug

External knock sensor input to module

1x 3 pin

Ethanol sensor

Ground, 5v, Digital input

1 x 8 pin plug

Trans module plug

ground, 5v, 6x digital inputs

2 x 3 pin

analog future expansion

ground, 5v, analog input signal

1 x 6 pin plug

external relay module

5v, ground, 4 x digital outs

1 x 5 pin on board Header

HC-05 bluetooth Module


headers/modules to centre of board

plugs to side and rear - stacked for easy side access via custom enclosure

After re-avaulating we feel the best route is a custom sheild design which will use
1. Mini mega 2560 plug in module

2. 36v-12v Power supply module

3. HC-05 Bluetooth module

4. MAX6675 Thermocouple Module

5. Our our custom Knock sensor module 5 pin

6. Stacked header connectors for external sensors, switches, comms, expansion.

We are using modules as this will cust down on complicated incircuit designs and time, and will allow easy replacement or upgrade in future.
