@nevorek

Good day. I can work in KiCAD and AD, but prefer AD. Some past work you can look in my portfolio. In PM i can provide more works with TypeC (power delivery, SuperSpeed hub) and ESP. > Acceptance 1. I prefer to place components on one side - more conveniance moune, cheaper assembly. But double-sided components mounting its good failback. 2. I know about ESP GPIO quirks. 3. I know about placement rules for such modules. As i said, i can provide past work examples. 4. Got it. About suppliers. I can provide for all components as many suppliers as can. For example: Mouser, DigiKey, JLC. Plan: 1. Schematic - 1-2 days. Most of time will spend for components searching and accurately set components properties in CAD. 2. Layout - 1-2 days. Task - 1 day and one daya for checking and fixing.

Hi, We reviewed your requirements and this project aligns perfectly with our experience in ESP8266/ESP32-based embedded hardware, IoT systems, and production-ready PCB design. We have designed custom development boards with sensor interfaces, USB power, data logging, and reliable wireless communication, ensuring clean layouts and easy manufacturing. We can design the complete schematic and compact PCB, including ESP-12, USB-C and external DC power input, regulated power supply, microSD logging, UART/SPI/I²C headers, GPIO breakouts, level shifting, and clear silkscreen labeling for an educational trainer. Special attention will be given to ESP8266 boot-safe GPIO selection, antenna clearance for strong Wi-Fi performance, and DFM-compliant routing to ensure a successful first prototype. Please visit our profile and portfolio to review our previous ESP-based PCB and embedded hardware projects. Timeline: 7 Days Budget: ₹16,500 (We can discuss the budget further after reviewing the complete project scope.) A few questions: Do you prefer the ESP-12F module, or should we recommend the most suitable variant? Should we include an onboard USB-to-UART programmer or only a programming header? Are there any specific sensors or modules you want the trainer board to support? We are available to start immediately and will provide regular progress updates. Regards, M&C Eng

@djalltra

Hi Your trainer kit is well defined, with clear functional and manufacturing expectations. I will develop the design in KiCad, starting with a schematic that keeps all ESP8266 boot critical GPIOs free of conflicts while providing clearly labelled headers for digital, analog, UART, SPI, and I²C interfaces. The power section will support both USB C and external DC input with proper regulation, protection, and the required 3.3 V and 5 V rails. Level shifting will be included where necessary, and the microSD interface will be laid out to maintain reliable signal integrity alongside the Wi Fi section. Component placement and routing will preserve the antenna keep out area to minimize RF performance loss and meet the RSSI target. The final package will include Gerbers, drill files, pick and place data, BOM with readily available Mouser or Digi Key components, and complete KiCad source files with concise design documentation for future revisions. Previous projects include ESP32 and ESP8266 IoT controller boards, sensor interface modules, data logging systems, and wireless embedded designs prepared for fabrication with complete manufacturing outputs. The first pass Gerbers can be delivered within 4 to 6 days, with updates provided throughout the design process to ensure the board is ready for fabrication without unnecessary delays.

I am committed to completing your project with accuracy, professionalism, and on-time delivery. I look forward to contributing to your trainer kit series.

@BLAZETECH100

I bid 2 days at your starting tier because engineering custom ESP hardware (autonomous flight controllers, UGV breakouts) is my daily work. I already have field tested KiCad templates that solve your exact challenges. Since bids here are public, I won't list the exact strapping pins or USB-C pull-down values for competitors to copy. Just know your constraints are baseline requirements in my standard workflow: • Boot-mode safety: I use a strict hardware-strapping isolation strategy so students cannot lock the boot sequence via sensor headers. • Wi-Fi RSSI (<2dBm drop): I implement strict RF protocols and multi-layer copper keep-outs, matching Espressif reference designs perfectly. • Power & SD Stability: I will design a seamless Diode-OR power multiplexer for USB-C/DC inputs, and decouple the micro-SD slot to handle transient current spikes that notoriously cause ESP brownouts. At 80x60mm, there is ample room to group UART/SPI/I2C headers with intuitive silkscreen bounding boxes tailored for a lab environment. I will deliver the KiCad source, 0-error DRC Gerbers, and a Mouser/Digi-Key verified BOM. Are you including an auto-reset circuit (via DTR/RTS) so students can skip pressing a BOOT button to flash? Message me to finalize hardware details and I will start the layout today.

@UserM42Blore

hi, I can execute this project using kicad to create the schematic and pcb. The Schematic , after approval will be taken to PCB layout and design. The first draft after approval and discussion we can go for trials and production thereafter. I have worked previously on creating orcad and eaglepcb, for power electronics.
