Convert push button switches on microcontroller boards to electronic switches (GPIO controlled)

$30-250 AUD

Posted almost 7 years ago

$30-250 AUD

Paid on delivery
The project is about converting a "mechanical switch" ( push button) to an "electronic switch" on a embedded board ( Example: RB Pi or Aurdino). The control voltage to the electronic switch is provided from a GPIO pin. 1. A sample embedded board will be provided 2. Electronic components required for switch ( ICs, restistors etc) is to be chosen by the designer 3. Push switches on the board can be left as it is 4. Switch should be designed considering all the current/voltage/impedance etc so that it works reliably over long periods of time 5. Follow a test criteria so that the switch works reliably over extended period. This will be one of the acceptance criteria. Deliverables: 1. Switch circuit/PCB board 2. Simple document describing the criteria that lead to the design ( Current/voltage/impedance during ON/OFF state) 3. Switch should work reliably for 24 hours under software control ( Locally tested after delivery)

Do you mean by electronic switch Solid state Relays? If you view my portfolio there is a design where a ARM uC controls 16 such switches, (among other things) Solid state relays works on AC/DC. depending on how may switches you require it is cheaper to use a Arduino Uno board.

Hi! I have fairly good experience with embedded systems and have designed several devices that make full fledged use of digital and analog electronics. I also have hands on experience with system on chips (SoC) that can cut down the project development time by many folds and also ensure the best in class signal integrity and low BOM. I have successfully designed and tested various circuits that make use of discrete solid state switches such as MOSFETs, BJTs, relays etc. I will be happy to assist you in your project.

Hi, I am keen to discuss further the details of your project. If the switches are now used in conjunction with GPIO, why do they need to have their current/voltage properly characterised? I think the most important thing if you need them to be reliable and have a long life is to choose a switch that will have a high number of cycles guaranteed by the manufacturer. I am in Brisbane so we might be able to discuss your project at a convenient Australian time. Best Regards, Gabriel

hi sir i am very good at pcb design and electronics in general, i read the description and understand what you need, but we need to discuss more as i have some questions for you to help me fully understand what you need, and confirm our agreements about that design initially, my price is for design and gerber files only, if you need working prototype that will be another cost, and we have to talk about that at pm, let me hear from you, at my reviews and portfolio, there are previous works related to electronics and pcb if you need to look regards
