We are developing LCD display for our application, Basic concept and major component selection is done by inhouse team in order to expedite project we are looking for developer who will design circuit based on our brief and later design PCB for the same circuit for next stage.. PCB design has to be on KiCad
My electronics knowledge is very limited but I'm trying to build a light setup for a 12V car. I have six different lights that need to be able to flash or stay on continuously. The lights will be controlled by 12V SPST switches. 1. Two headlights that will either do alternating flashing or stay on continuously. 2. Two Fog Lights that will only do alternating flashing when the headlights are alternating flashing. 3. Two taillights that will either do alternating flashing or stay on continuously. a. One switch should turn on both the headlights and taillights in continuous mode. b. One switch will turn on the alternating flashing of all the lights.
Looking complete PCB development inclusive of simulation, source code, microprocessor programming, and Bluetooth App, schematics and Gerber file development and actual working pcb prototype along with aux board that will monitor input of up to 10 - 12v AGM batteries in series / 20 with aux board coupled to second battery bank which is parallel with primary which monitors bank(s) for under and over voltages during charge and discharge. Board capabilities are to read voltage, current, charge state and calculate Ah, as well as CCA of each bank as well as the total bank voltage parameters. Board must be capable of selecting fault battery if not within Voltage, Ah or CCA parameter determined by dip switch settings or user programmed firmware. Board is to be capable of constant current equalization of bank up to 10-100a [option is only accessible trough firmware program key in OPTIONS for aux system board programming] Board will control voltages ranging from 12vdc to 138vdc utilizing 4-digit 7-segment voltage monitoring display with piggyback LCD information display along with 10 two color led green (normal) and red (fault) led to pinpoint fault location battery in bank array, can also be achieved through software and LCD display coding. Battery Monitor is to be BlueTooth capable with ability to send and communicate with other modules such as battery charger Android and Iphone Board must utilize dip switch voltage selection hierarchy to set number of batteries in bank and voltage along with Potentiometer to set over and under voltage range (on) and range (off) action coupled to drive a 20 amp relay to invoke other modules. Total 11 relays on main board 1 for bank total and 1 for each battery in its bank Board shall feature Aux plug to accommodate backup Bank monitoring of the same sorts oftentimes ran parallel to primary array. Aux board shall have input up to 10 battery inputs assigned by user (dip switch) as well as 10 sequential on/of relay actions from monitoring each battery
we need device engineer freelancers. you have to know about PCB.
Hello - I need to make a PCB that will have a total of 8 Solid State SPST relays, an Ardiuno nano (or similar functionality since I'm only using the digital pin functionality), 4 LEDs, and sturdy mounting connectors for a wiring harness to connect the following: Solar Power Wires, Lithium Ion 18650 Battery stack, Solar Battery Charger, Car Battery Charger, Wall Battery Charger. You could build in the Solar MPPT charge controller into the circuit. I can get single line diagrams for all of this. Please let me know your thoughts. I would like to have milestones for a gerber file, one for the software, and then a milestone for a tested fully functional product. Please let me know your thoughts. I already have the arduino code written and this system is functional, but I want it all integrated into a single board.
