I need a custom gerber file (compatible with ) of esp32cam for a round ⌀32mm board. You can only remove card reader. All pins arround the board like the lilypad board. Camera objectif should be on center of the board. To avoid bot, start your proposal with "Hi Ju"
Development of Ultrasound PCB Need the generator to work around 1.7Mhz freq. with 8 outputs Need that the PCB with impedance matching circuit(to the transducer and electronic) thanks *please contact me only when you have an experience with ultrasound designing *Please be aware that I need full work: design-manufacturing-assembly-testing and shipment to be a full working prototype the payment will be only for working prototype attached specifications(can be change)
We would need to create a hardware to sit on a raspberry pi or an arduino and connect to vending machines control boards. We would like to read data from the vending machine through the MDB protocol and send instructions to the vending machine. Above is the requirements. Please don't bid on this project unless you got previous experience with mdb protocol.
We have a low voltage project that requires expert advice and consulting on. Plus design and stamp for approval with cUL and UL I need an electrical engineer that specializes in low voltage to help us put our design into drawings, and stamping for approval. Along with providing their expert opinion on the design. IMPORTANT: The engineer must have an engineering stamp
Examination of analog and digital device models for analysis, design, and simulation of transistor level electronic circuits, emphasizing Metal Oxide Silicon Field Effect Transistors (MOSFETs); fundamental single transistor configurations; frequency response, feedback, and stability of multi-transistor circuits, such as current mirrors, differential amplifiers, voltage references, operational amplifiers and data converters; complementary Metal Oxide Silicon (CMOS) implementations of static and clocked digital as well as mixed signal circuits.
The PCB board needs to cover followed: 1. Board supply from 8-36V (TPS54240) 2. Three analog inputs to measure volts from 0-36V (ESP32 ADC) 3. Three analog inputs to measure current and volts from 0-20A using INA226 via I2C 4. Two Digital inputs with high voltage protection, working voltage 0-36V 5. Two Digital Outputs Open Drain with N-MOSFET (AO3400) 6. One serial input for SIM7080G LTE/GPS via PCIe (ESP32 - Serial 2) and sim card slot on the main board 7.

I am using split rail supply using attached circuit. Total current draw is nearly 100ma at 24v input. Current situation is PNP transistor getting hot. So if current will increase it can cause the issue. What cout be the solution to improve the situation.
we need to designe circuit that can transfer any text ino digital form and from digital to analog to antenna. we have antenna ready designe that need to be attach to circuit. So Basically via computer software alpha numeric data will send to coil.
The awarded freelancer will provide a technical document with suggested improvements and general review of 1 PCB design with the intended purpose of improving the design in order for it to pass CE and FCC compliance tests. The review must take into account possible issue with EMI/EMC compliance norms and low voltage directives.
Hi, I'm looking for help assessing & optimizing capacitive touch accuracy across various hardware/software combinations. Specifically, we will work with the Apple iPad Pro & Apple Pencil 2, the Surface Pro 3, and the Wacom drawing tablet. The job will be to help create a scientific system (e.g., miniature experiments) so that we can test these aspects. The goal is for us to optimize the capacitive touch precision in the apple products (specifically within our software) as compared to the other combinations. We have laboratory equipment that can help us in this experimentation and are open to purchasing additional equipment if the pricing is reasonable. I will then conduct the experiments using my setup via zoom meetings. We can make adjustments live, troubleshoot togeth...
I need a custom PCB to be designed for my electronics project. The PCB design should be provided with Gerber files, drill files and any other details required for completion of PCB manufacture. My need will be for 3 to 4 projects that will be needed in a span of 1-2 months. Need immediate turnaround once order is placed.
