Hi, feel free to bid if you have experience with ESP32,LAN8720,POE
1. Description of the device
LAN / POE gateway based on the following components:
- LAN8720
- ESP32-WROOM-32D / ESP32-WROOM-32E (pin compatible)
- The POE module should be an option, from the widely available modules from Aliexpress, but if there is enough space to be included in the PCB, then by default. An example of modules available on Aliexpress: DP9700-5V, DP9900, DP1435, RT9400
- Expansion board based on mini PCIE or 2x6 pin connector on both sides for good fixing.
2. Technical requirements
- Power supply via Micro-USB and POE optional.
- DC power supply 3 V, 1-2 A, It is advisable to use a DC-DC converter from 5V to 3V.
- Dimensions of passive components starting from 0603.
- the components used in the PCB must be available on [login to view URL] for SMT assembly, preferably in the base category.
- Output pins ESP32 UART1 (RX & TX) or UART2 (RX & TX), depending on availability, to the expansion board.
Including also VCC, GND also 2+ any GPIOs, if possible, then all available GPIOs go to the expansion board
- Jumpers required to select between ESP UART and UART expansion board.
- The button used on the PCB should restart the module (RST) and also get a contact on the expansion board.

Hello,
I hope this finds you well. I have just seen your project requiring;
Electronics
Microcontroller
Electrical Engineering
Circuit Design
PCB Design and Layout
I believe that my 10-year experience in this field is what you need right away. Avoid the headache of looking further.
Let's save time and focus on the real task. My proposed timelines and budget are just placeholder and an open for negotiation to increase or decrease as per the full requirements at hand.
Allow me to prove how better my review can be. Smile all the way! Click the message button, so initiate the conversation.
