Hello, Thank you for the detail. I have checked the schematic that you have attached, it's not much clear -> It seems USB UART connector is for programming purpose? right? -> Also send me schematic pdf form (if possible) so, I can check the voltage regulator part and RTC part. I have designed the ESP32 and RTC based PCB before as clients requirements. I can design the PCB and modify the schematic (if require). Questions: -> In how many layers you need this PCB? -> What should be the dimensions? You can send me details at any time. Thanks, Chanchal k.

I have long experience with PCB design. I have worked with low-speed , high-speed and power boards. I use Altium Designer and Eagle, and I deliver neat layout that conforms to your dimension constraints and the manufacturing constraints. You can see samples of my previous work on my portfolio. More to be discussed once you contact me . BR, M.T.

Okay! Surely, We can verify your Schematic done in KiCAD. We are a professional team in Embedded hardware & Software development. We will design a PCB layout on the basis of circuit. Please come for the PM. You can review our PCB design work in our portfolio:- https://www.freelancer.com/u/intellisenseIN We will be glad to hear from you! Regards, Intellisense Technology

Hello, My name is Andrei, i am a Romanian IOT Developer with a lot of experience in IOT projects and automatics . I have look at your schematic and the is necesary to calculate the resistors and the transistors, because there are some mistakes , the 2N2222 transistor is saturated with 100ohm resistor , need do be some where between 3K3 to 6K2 , but this is calculated even with the max I on the pomp. To introduce me and my services . I can work with all types of Microcontroles programming in C , C++ , Mikro C , CCS C , Atmel Studio , Arduino , gcc . Creating Schematics and PCB in Kicad , Eagle , EasyEDA and Proteus (+simulation). i have an workshop full of parts and the infrastructure to build PCB and test the solution end to end using special tools (Spectrum analyzers , oscilloscope , logic analyzers ) Derivable on the project : Schematic design PCB Design Gerber files for manufacturing Build of materials - Farnell Mouser Digi key TME As an additional service i can make you a full working prototype and ship to you. I deliver clean code and clear solution for all type of applications . Regards, Andrei

Hi Sir. As a Circuit Design Expert and PCB Design Engineer, I have expertise in PCB Design Layout using CAD Platforms that include KICAD, Eagle CAD and Altium Designer. Due to vast amount of experience in KICAD, I found myself capable of this job. I am sure that you are satisfied by my work. Thanks.

I can help you with this. I have done a musical keyboard, a capacitive touch volume control board, and a musical synthesizer board in KiCAD. I have 15 years layout experience with PADS, Altium, Kicad, Eagle, and EasyEDA. I'm in Austin, TX, USA.

i am a KiCad designer so i can design your PCB,it's quiet simple one except ESP32-WROOM. the footprint for ESP32-WROOM not available in KiCad library (don't worry i can make a custom library with reference of it datasheet). And what about the motor current that you are using is PN2222 is enough? And i think there will be change in motor connection too.... 2 pins having both ground one is as switch and other is gndreff, do you mean that? please give details about your pump.....

I can check whether your schematic is ok or not. and i can make this pcb as you want . I want to use proteus or eagle cad . If you want then i can also use ki cad.

I am an experienced embedded systems engineer. I found that your RTC lacks a crystal， and I2C lacks pull-up res. My software is Altium designer, I can export PDF schematic for you. I will provide quality service and I am looking for customers who can cooperate for a long time.

Hi sir i know how ESP32 work I will verify your pcb design and send you change if there is problem Thanks you for reading my bid
