This is a new storage device with fewer components and using an arduino NANO instead of an Arduino UNO.
You will also need the following modules:
- LCD 16×2 with parallel to serial module
- SDCard module (5V support)
- Arduino Nano
Also some 3mm spacers for the LCD (4) and for the board (4).
Bill of materials:
- 1 MAX232 i.c.
- 1 Capacitor 100nF
- 5 Electrolytic Capacitors 1uF
- 1 Electrolytic Capacitor 220uF
- 1 LED Diode
- 5 Resistors 10KOhm
- 1 Resistor 320Ohm
- 5 tactile buttons 4-pin.
- An RS232 female PCB connector.
- 2 pin terminal block (for power)
- 4 pin straight SIL connector for the LCD
- 5 pin straight SIL connector for the SDCARD Module
All Modules should be soldered on the PCB, no female connectors to save height.
It is better to solder the parallel to serial module to the LCD and then also solder the serial module to the PCB.
You should supply the board, through the terminal block, with 5v power.
*** NOT TESTED YET but it should work.
