FAQ section :

---------------------------------------------------------

Do NOT use an external power supply when connecting to a PC over USB.
If the external power supply doesn't have good ground isolation it may cause problems and even damage either MegaDrum or a PC.

---------------------------------------------------------

The components must be located on the side of the top white silk screening.
You just need soldering on the bottom side.
Holes on the pcb are copper coated to connect both sides of the board.

---------------------------------------------------------

Component label = PCB label

yellow violet black gold = 47
brown black brown gold = 100
red red brown gold = 220
yellow violet brown gold = 470
brown black red gold = 1k
yellow violet red gold = 4k7
blue red red gold = 6k2
brown black orange gold = 10k
yellow violet orange gold = 47k

15 = 15pF
22 = 22pF
104 = 100nF
D224 = 220nF
470nk = 470nF

12.000 = 12MHz
16.000 = 16MHz
20.000 = 20MHz

There is no polarity for these components

---------------------------------------------------------

For the LCD, you can use for the "R lcd" :
- A 100 ohms resistor or less for the White / Blue LCD
- A 470 ohms resistor or less for the Blue / Black LCD
- A 47 ohms or less or no resistor for the Green / Black LCD

---------------------------------------------------------

The bigger than the other resistors provided, with a SILVER ring, is the inductor, go on the spot labelled "1mH".

---------------------------------------------------------

With your Atmega32 kit, you must use the 16 MHz crystal, go on the spot labelled "16MHz 20MHz".

---------------------------------------------------------

Atmega32/324/644 all have the same pinout.

---------------------------------------------------------

Red push-buttons must be wired between the "C" pin (common) and the "NO" pin (normally-off).

---------------------------------------------------------

1N4148 component (diode) has a polarity.
On the PCB, the square pad is the positive.
On the component, the black ring (or yellow) is the positive.

Will you accept custom orders? For example, the so claimed kit with only the board and the IC's?

I changed the Kit 1 to propose the "so claimed kit". ;)

How do you decide which crystal to use?

With Atmega32-16PU, you can use the 16 MHz crystal.

Atmega32 is already programmed with the multiclock bootloader and the last firmware.

I'm sorry to ask these stupid questions but... Will I manage with the Kit 2 if I use it only with PC, or are the (keyboard)buttons and the LCD still necessary? Is the MIDI connectors necessary, or can it be used via USB? I'm trying to save money so, can DIY triggers be directly connected to v2.8 PCB without using plugs or any other devices or components? I will probably do those plug inputs later. I will not be using hi-hat controller pedal, or those other fancy 3 zone things for now.

You can control the megadrum directly with the PC with the MCT software (Megadrum Config Tool).
The MIDI connector is not necessary, it can be used only via USB.
Triggers can be directly connected to v2.8 PCB, but it's better to pass through connectors.

So this means that the LCD and the buttons are not necessary when connected to PC?
