Custom model cases are print-ready
Choose and print your enclosure with preferred colors and surface patterns
I suggest a cool-white (signal white) base and a dark front plate with a nice carbon fibre pattern.
- esp32 D1 mini controller with USBC
- pn532 NFC reader
- grove angle connectors
- grove cables
- hw040 rotary encoder
- dupont cables for hw040
- M2.5 10mm screws
pn532 connector:
- GND: GND
- VCC: VCC (+5V)
- SDA/TXD: IO21
- SCL/RXD: IO22
hw040 connector:
- CLK: IO18
- DT: IO19
- SW: IO23
- +: +3.3V
- GND: GND
ESP32 D1 mini will fit perfectly into the bottom part braces
Built-in LED is used as confirmation light. Print the led peg with clear filament and it will give great results
I preffer soldering the grove angle connector to the PN532 NFC board
Just use the force ;-)
Remember to set the DIP switches to 10 to enable I2C. Correct position for I2c is marked by yellow lines.
Everything will fit into the enclosure.
Use 10mm M2.5 screws (nfc board, volume encoder, front plate).
