Raspberry Pi I/O Extender Modules -- 2
Budget: $250 – $750 AUD
I am looking for a freelancer to design and develop
- Enhance / modify current design of our Raspberry Pi I/O Extender board.
-- Adding into it a 'daisy chain feature for the daughter boards(see below).
- Design 'daughter' / 'child' boards which can be hooked up in a chain talking over I2C, SP2 etc
Function:
- Daisy Chain / Connect through RJ45 Cables / headers.
(Data and low power)
- Have a high power input / output for motor. (opto isloated)
- Input pins, and output pins.
- Dip switch block for 'position' in node chain / daisy chain.
- OLED screen for displaying basic Info(2.42 inch)
- Control string of WS2812 LED's
OLED screen will simply displays 0-999.
and basic connection / startup / config options.
The idea is relatively simple.
There is 8 stations where these boards sit at.
'Client Side'
- A switch is triggered, counter goes up in increments of 1 to a maximum of 999.
- When switch is triggered MOTOR 1 runs on a Time Out for 5 mins. If user triggers switch again Time Out is reset.
- At set intervals on the counter, 50, 100 motor 2 is triggered momentarily.( eg 5 seconds).
- When counter reach's 500 or 999(user configurable) then a trigger is sent back to main raspberry pi board.
- Running total of all 8 machines should be sent back to 'gathered' on main raspberry pi board/breakout board.
- When running total on main board hits 999 then or counter from nodes/satellites hits 999 then a MOTOR is triggered from main Raspberry Pi board.
Interface:
- I2C
- SP2 or other
Form Factor:
- Custom size
Ideal Skills and Experience:
- Experience in designing and developing Raspberry Pi modules
- Proficient in programming languages such as Python
- Knowledge in I2C interface and circuit design
- Familiarity with custom hardware design and manufacturing
The project will involve designing the circuit and PCB layout, programming and testing the module, and producing a prototype. The successful candidate will be able to deliver a high-quality and reliable solution that meets the specified requirements.
I will need hardware and basic software / firmware coded.
