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. Have also uploaded Image of current Extender Board.

Dear Client, Thank you for providing a clear description of the requirements. I have carefully reviewed them and am confident in my ability to estimate the deliverables and timeline. It is understood that the project entails designing a node device with an OLED display, motor control with a timer, and the hardware and firmware necessary to support these functionalities. Additionally, communication between the nodes and the motherboard (RPi) will be achieved through a daisy-chained series connection, and the nodes will be addressable using a DIP switch. Regarding my experience, I have worked extensively with RPi and IO expander modules for RPi, which has equipped me with the necessary skills and knowledge to successfully undertake this project. Therefore, I am enthusiastic about submitting my bid. Outlined below are the deliverables I will provide: 1. Circuit design and comprehensive review 2. PCB layout design using KiCAD 3. Building of prototypes (Please note that the hardware cost and delivery expenses will be borne by the customer) 4. Firmware development for the IO expander module 5. Firmware development for the RPi 6. Documentation, as per your specific requirements I assure you that I will meticulously maintain and deliver all source codes, along with a comprehensive change history. I eagerly await your response and am open to further negotiations, should they be required. Thank you for considering my proposal. Best regards, Kavin
