I have the full schematic for working legacy PCB. I need it redesigned and modernised into a new board using current components, while keeping the original board size, mounting holes and connector positions. The old design uses PIC18F8722, FT232RL, TDA7465, video switching and RCA outputs. The new design should replace those with STM32 native USB, modern audio DSP/codec, protected coin inputs, modern power regulation, and custom firmware support. This is not an exact clone. It is a modern drop-in replacement using the original schematics as a reference. Key things :- Keep: * Board size: 168mm × 206mm * 6 mounting holes * USB-B position * Existing amp connectors * Mic input * Coin mech interface * IR receiver/service button * J8 motherboard audio input Remove: * RCA sockets * Vi...

I have a small home-automation module that needs a reliable touch interface, so the task is to engineer a 5 V circuit around the TTP223 that cleanly switches between high and low digital levels whenever it is touched. Precision in sensitivity and long-term stability matter more to me than squeezing out the very last microamp, yet the design should still sit comfortably in standby without wasting power. Key expectations • The sensor must tolerate normal household electrical noise without false triggering. • Output logic levels must be directly MCU-friendly (TTL/CMOS, active-high preferred). • Component count should stay minimal; surface-mount parts are fine. • Any necessary debounce or filtering should happen in hardware rather than firmware. Deliverables 1. ...

I have a concept for a small control board that will act purely as a communication interface; the brain must be a microcontroller and every line on the board will ultimately speak SPI. I need the complete journey covered—from schematic capture through to a working prototype—and a simple companion application that can configure, send, and read data over that SPI bus. Hardware I want you to select an appropriate MCU, lay out the PCB, generate the BOM, and produce production-ready Gerbers. The board will only need the essentials: power regulation, the MCU, an SPI header, and whatever discretes are required for reliable signalling. Options such as UART or I²C might be added in a later revision, so leave enough pins and routing headroom for that future expansion. Firmware ...

I need an analog circuit designed from the ground up and then laid out on a production-ready PCB for a consumer-electronics product. The finished board must operate as a single, unified control unit that fits cleanly inside a dedicated enclosure, so component placement and overall footprint matter as much as the schematic itself. I need an integrated control panel which houses two subsystems. One is water pumping line and the second is uv disinfection line. The circuit diagram for both subsystems will be provided . Kindly provide an integrated one and a pcb design for the same.

I’m building a two-layer, donut-shaped PCB around ESP32-WROOM-32U. The outer diameter must not exceed 92 mm, the inner cut-out must remain at least 54 mm, leaving the 19 mm wide ring as our only real estate. Please respect the antenna keep-out zone on the outer edge of the module. Inside that narrow ring we still need to route: Quectel L80 GPS on UART, a MAX98357A audio amp over I²S, a DS3231 RTC on I²C, an SPI-driven MicroSD slot, and a single raw copper touch pad positioned on the perimeter. Power comes from a USB-C connector that sits on the edge; horizontal or vertical placement is fine as long as it follows the board outline and brings out both 5 V and a regulated 3.3 V rail. You may work in EasyEDA or KiCad—either format is acceptable. Please apply the board ...
