Developer a microcontroller (in the beginning could be Arduino, etc. - later own controller hw) application that does control temperature on a device and modifies performance settings (volt, amps) based on some characteristics. It uses input and output information via a touch display or OLED/steering buttons. Needs to control also a few actuators/relays.

Can you calculate a matching network for Bluetooth (2.4 GHz) and GNSS (1559-1610 MHz) using lgnion MXTEND DUO NNO3-320 antenna? PCB length and width (mm) - 60*15 mm.

I have a Custom Mechanical Keyboard which has switches soldered into a PCB by two solder joints. As I have little experience Desoldering I was looking for someone on here who could do a good job Desoldering the board and sending the two parts back separately.

need someone who develops for arduino uno sketch that can read and write EMV smart cards. So you don't need any intermediate hardware, which directly communicates the Arduino to the IO, RESET, VCC, GND and SCK pins of the chip. The libraries that you have available only serve to understand a little of how communication is done, as they are not functional. I provide research material.

Design a PCB for a circuit design.

I am after a wiring diagram and a parts list on creating a handheld, palm sized cooling device. Ideally, it will need to be double sided with a large surface cooling plate on each side, a rechargeable battery whereby the device can remain at a consistent cool temperature (8 degrees celsius up to 16 degrees celsius), be able to stay at these temperatures for at least 20 minutes, have an on off button, a small lcd screen to display the temperarture of the device and a way to adjust the temperature.

I require a programmer to develop both firmware and GUI for a waveform generator using AD9106 and STM microcontroller You must have relevant experience in device programming along with schematic and pcb design. Fusion 360 access desirable More information will be given to suitable applicant for this project.

I have a pcb from a usb hub, which I can send you a photo of. I need to have a gerber file of this board and probably a few modifications done to it. This pcb the will then need to be produced, so the gerber file needs to be made with production in consideration. If you need any details, I will of course try to provide as much as I can, but I only have a real board and the specifications for the ports.

Hello, I am looking for someone to design a PCB board to control a small electric water pump. The pump will turn on for 2-3 seconds every 30-60 seconds and will check for water. If the electric pump has a load on it (from water) the pump will stay on until the load is no longer present. I would like this to use a microcontroller so we can reprogram and change the check time (anywhere from 30-60 seconds). Thanks

I am trying to work out a bespoke electrical circuit for a slave / tandem heating system which includes a gavity fed standard Y configuration CH and HW gas boiler with a mid port valve and now a slave pellet boiler stove. The pellet boiler stove has an integral pump which activates when the water in the boiler reaches 70c. At this stage I want the system pump to be activated and water to be pump into the HW cylinder until the cylinder thermostat reaches 70c at this stage the mid port valve would activate both grey and white wires to dump ongoing hot water into the central heating. Importantly I want it to do this using the existing system pump, mid port valve and cylinder thermostat that is part of the gas system. It is the case that the two ststem will not run at the same time. This ...

My project consists in a circuit board which is responsible for communicate with the internet and triggering 4 electronic locks of 3V 1.5a using relays. Due to high inductance generated by the electronic locks, it is necessary that the circuits of the locks are isolated from the microcontroller circuit to avoid crashes/bugs. The board must have a circuit of lithium battery which must provide an autonomy of at least 8 hours. This circuit will be activated when the site is without power. To connect the ESP32 to the internet, a 4G modem is connected to the board. The board must have a female USB connector to power the 4G modem. The female USB connector must have a circuit capable of having its power interrupted by a command sent by an ESP32 I/O port (After a few hours of initerupt...
