I have a working PCB designed in Altium. Since we will do all future work in KiCAD, this project needs to be converted to KiCAD 6.0. The PCB has a MCU that receives data from two SPI radio modules and relays the data to USB, Ethernet and Bluetooth for further processing on a PC. The PCB also has two RGB LEDs, battery management, barometer, GPS module with active antenna detection, speaker and a few other features. The attached BOM contains almost all components. The PCB size is 63x87 mm. It's a conventional four-layer PCB with two power planes. The resulting KiCAD project will have identical schematics. The CAD footprints, layout and outline will also be identical. CAD routing is not necessary to do, since any future work will require...
Hi, I am looking for a PCB designer to make me a custom Arduino shield. I need to connect various sensors and actuators to Arduino and have a computer connected to monitor and control those things. I have defined the shape of the PCB. Also, I would like to hear ideas and improvements from the one who will make the design. It is clear to me, that the ones who are professionals in electronics know the best way to do it. In the attachment below I send the schematic and basic logic. We will define all the placements at the zoom meeting.

Need some help setting up some simple codes for my pcb board running esp32. I use to program myself, but its long time ago and i don't have time to deep again. My pcb board has a lot of capabilites. But to start with I only need it to start the water pump (pin 12) for 2 min and then off for 10 min. Repeat. In addition the lamp needs to run for 18 hours on and 6 hours off. I will need to expand the code as i activate more functions on the pcb board. But for now thats it. There will be 3 task for this job: Task 1. Start

...and read the value of a 4 byte counter on an external clock (25 to 50 MHz). The 6 x 2 bytes values of the 6 analog signals, plus the 4 bytes of the counter and 1-2 bytes for with the board identifier will be streamed via Gigabit ethernet as UDP packets (about 1000 x 20-bytes events in every packet). The board should sustain a trigger rate of the order of 1 Million per second or higher. This project should be implemented on a MCU, as it is to replace a similar board based on FPGAs. The MCU will read the external ADC (6 independent ADCS able of at least 1 Ms/s each, at 12 bits). A 32 bits MCU based on multi-core ARM at 1 GHz or more would be required to handle the trigger rate. At a first stage, the functional analysis and simulation of the board should be presented and approv...

This is a HW (hardware) and FW (firmware) project: - You will have to develop the electrical connections, the 3D view and the Gerber of the "" file (I will manufacture 6 boards for my POC). - You will have to also provide the Arduino Code to test each part and functionality of the circuit - I have already ordered all breakout parts listed in the "" file, so you have to stick to those parts and cannot use any other one - Once I receive the PCBs from the manufacturer and have mounted all the breakouts there, we will test the circuitry with the code you provided - In case of issues, we will connect on live chat (Teamviewer, Meet or similar) so that you can check the code and or the connections. I will have 24x7 remote control to my development laptop, so that you ca...

(Please place a bid only if you have done a project similar to this and can provide a reference I can call to verify. DO NOT bid otherwise ) I need a dimmer designed for a LED driver made by Inventronics (model number EUD-096S350DTA) . See the attached data sheet. The dimmer will be powered by auxiliary output of the LED driver. I would like to have a rotary device on dimmer to change the light level. It should snap into 10 specific steps for %10, %20, %30, … %100 light level. It will have the effect similar to reducing the current going to LEDs to %10, %20, %30, … %100. The BOM should be put together from parts that are in stock with electronics components distributors in North America. Deliverables are schematic design, PCB design and parts list.

Hello, I have a pcb with ESP32 S3 that has bluetooth capabilities. The bluetooth is acting as a server and receives connections from an iOS app and from another ESP32 S3 configured as client. Code is written in Arduino IDE. My problem is, I do not seem to have BLE 5.0 range results, the range is similar to BLE 4.0, which is around 5-10 meters. I have been doing some digging and it seems ESP32 S3 with BLE 5 has 3 types of PHYs (physical layers): 1M, 2M and Coded PHY. As far as I read, default is 1M? (which is BLE 4 range basically). My goal is to adapt my code in order to support 2M PHY (100m range or so) or even Coded PHY (500-1000m), so the BLE connection can work at more than 5-10 meters. Thank you! Marius
Hi Valery N. I want to start the PCB project. Please guide me trough step by step.
Please have a read through the attached specification. I'm very happy to answer any queries about it. My background is mechanical engineering with very little electronics experience, so the spec is based on my perceived expectation that it is technically feasible. I am receptive to feedback where you think issues may arise. I'm particularly interested in anyone who can introduce me to a PCB manufacturer (China based ideally) to accelerate the process. For clarity, we can flesh out the prototype cost in addition to the cost of the programming etc. kind regards, Alex
