eLabel board

I would like to hire the development of an E-Label board based on an ESP32 with some special features:
• Wemos LOLIN32 Lite (it must be this model because of the batery charger circuit)
• EPD display model GDEY037Z03 (3.7’’ B/W/R color)
• HAT adapter circuitry for interfacing the EPD with the Wemos: Not using the hat but integrating its electronic in our board; schematics are provided
• RGB LED
• Push button
• Qi charger (induction)
• USB charger
• LiPo Battery 504050 - 3.7V – 1500 mAH
• UHF-U9 Rfid tag§
• Magnet
• 3D Enclosure

IMPORTANT:
• Te price of the materials will be paid as an extra milestone and is not part of the price set for this project in Freelancer.

Mi priority:
• Lowest possible thickness.

Power consumption considerations:
• ESP32 will normally be on DeepSleep mode (~10 µA) and will wake on WiFi event (upload QR/EAN13/Text) on the EPD display.
• Estimated updates per day: 5
• Battery should ideally last several months.
• Battery must be rechargable over Usb.

Delivery:
• You will design, mount, test and deliver 3 full working devices.
• Before any final design you have to please contact me for an Ok.
• Test functions of the board, written in Arduino IDE, like for example: loadImage(img), clear(), getBatteryLevel(), getMacAddress(), connectToWlan(user, passw), setState(bool), setDescription(str) or whatever it will be required to test all functionalities of the board.
• Provide a 3D-printed enclosure for the boards. There will not be any switch slipping tray for the battery: the enclosure will just expose the display.
• CAD-Schematics for the pcb and the enclosure

Due date:
• 45 days

Additionally, following package can be paid extra if you want to provide it:
• Web App (very basic), writen in C#, where we can: (1) connect over the browser from a PC/Laptop, (2) comission a new E-Label with MAC-Address, (3) request all E-Labels conected now, (4) enable/disable E-Label with MAC xxx, (5) request battery lavel of all E-Labels, (6) request image beeing displayed on E-Label with MAC xxx, (7) Load image on E-Label with MAC xxx, (8) Clear display of E-Label with MAC xxx
• Enable OTA programming for a given E-Label with MAC xxx.
