I’m building a battery-powered prototype around an ESP32-S3 and need a rock-solid wiring diagram before I assemble anything. Once we start, I will share a complete list of sensors and modules, but you can assume they will be driven from a 9 V rail that must be stepped down where necessary. My priority is clear pin assignments, clean power routing, and reliable level-shifting so every device behaves exactly as intended. Your task • Draw a schematic / wiring diagram that shows every connection between the ESP32-S3, the sensors, any required regulators or level-shifters, and the battery interface. • Specify the exact GPIO pins you choose for each signal and explain any rationale or constraints. • Indicate decoupling, protection components, and connector types where...

I am building an integrated volt-ampere meter that also serves as a protection and control module for a pump system. The unit must: • Measure voltage and current accurately while reacting instantly to high/low-voltage and over/under-current conditions (these three protections are the top priority). • Manage a water-level subsystem that reads three stainless-steel probes plus one flow sensor, then drives two relays—one energises the starter circuit, the other keeps the motor running. Scope of work 1. Circuit and PCB: create the full schematic around a MindMotion MM32G0001A1T (or any other MM32 in the same family so our inventory stays unchanged), layout a compact single-board solution, and specify a CC display already stocked in-house. 2. Firmware: write clean, well-docume...

I have a small desk clock with a beautiful vintage edge-lit display, a bank of mechanical relays, and an Arduino doing the time-keeping. Unfortunately my first build was amateur—cold joints everywhere, wires stuffed into screw terminals, no strain relief.... Then a housemate dropped it. A friend at a makerspace has begun soldering bulbs in the propper layout to match the display but only completed the bulbs for 1 digit. They also started a ribbon connector for the bulbs to the relays/arduino/power section. I’d like you to finish the bulbs, get them connected, then cleanup the Arduino/gps-receiver/power section so it's mounted and ready for a case. I already 3d printed the display mount. • Flawless soldering on every connection, preferably on tidy perf-boards or a ...

My ESP32 Dev Module refuses to return anything when I send AT commands to a SIM800L red board. The wiring follows the usual guides: GPIO27 to the SIM’s RX, GPIO26 to its TX, grounds tied together, the SIM powered directly from a single 18650 cell. I’ve triple-checked every jumper and even dropped a 1 kΩ resistor on GPIO27 and a 2200 µF capacitor across the SIM’s Vcc–GND rails—still silence. I’m compiling the sketch for the standard “ESP32 Dev Module” target in the Arduino IDE and the board is on a direct USB cable to my laptop. Serial monitor shows the commands leaving but not a single character coming back. If you know this pairing well, I’m looking for hands-on guidance that quickly pinpoints what I have overlooked&mdash...

I’m migrating my current AMB82-mini daughter-board solution to a single, production-ready PCB built around Realtek’s RTL8735BDM module.

Essential upgrades • Integrate a DS3231 RTC • Add a LiFePO₄-compatible battery gauge with coulomb counting • Provide a full-size SD-card slot • Break out USB and SPI/I²C headers for easy access during development and in-field updates What I expect as a turnkey hand-off • Altium schematic and multilayer PCB layout • Optimised stack-up, impedance-controlled traces where needed • Manufacturing package: Gerbers, drill files, pick-and-place, 3D ...

I’m building a new IP CCTV camera that must clear India’s STQC certification, and the System-on-Module is the piece I want you to own. You should be comfortable selecting or custom-designing the SoM, bringing up Linux or RTOS on it, and interfacing a global-shutter image sensor through an ISP pipeline. Secure boot is mandatory; I’ll rely on you to create a trusted boot chain, sign the firmware, and lock down update paths so the final product is field-upgradable yet tamper-proof. If you already have experience hardening U-Boot, using ARM TrustZone/OP-TEE, or similar secure enclaves, tell me up front. Because we must pass STQC, every hardware and software choice has to come with traceable documentation. Expect to collaborate with my mechanical and compliance team on E...

I have a clear photograph of a double-sided PCB taken from an automotive control module and I need that board faithfully recreated from scratch. There is no schematic, component list, or labelled photo available—only the image itself—so the job calls for full reverse-engineering talent. What I need from you is a complete, manufacture-ready package: the schematic you derive from the picture, the routed board layout matching the original dimensions and hole placements, and production files (Gerber, drill, pick-and-place). A concise BOM based on the components you can visually identify will round off the hand-over. Accuracy is critical: track widths, via sizes, and copper pours must respect typical automotive reliability standards. You are free to work in KiCad, Altium, Eagle, o...

The existing PCB is functionally sound, but several components need to be swapped for newer equivalents and a handful of additional SMD parts must be integrated without altering the overall board footprint. The layout will stay largely intact; the job is focused on component-level edits rather than a full redesign. Key work: • Replace specified components with the updated parts listed in my BOM draft. • Add two new SMD devices (a low-profile DC-DC converter and a temperature sensor) into the current schematic and layout, observing clearance and impedance rules already in place. • Update the BOM, pick-and-place, and assembly drawings so everything aligns with these changes. Deliverables: • Revised schematic and PCB layout files (Altium Designer preferred, KiCad a...

I’m working with a Diode Laser Board and I need a custom receiver that can plug into that setup, track the machine’s positioning in real time, and instantly flag any faults it detects. The idea is to have continuous monitoring so I can see where the laser head is at any moment and receive automatic alerts if something drifts out of spec or a component misbehaves. Ideally, the receiver will take positioning data straight from the board, process it with minimal latency, and expose a simple interface—serial, USB, or another protocol you recommend—so the data can be displayed live on a host PC or microcontroller dashboard. Reliability is critical, so built-in error detection should cover signal integrity, unexpected motion, and any other obvious fault conditions you id...
