Assemble MozMo
How to assemble Mozmo
Mouser Cart http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=1c71905cf1 note : they don’t have
- the pots
- the jack connectors
- the 12 mhz resonator I am using
- If you dont have a 5V bus and If you plan to add the 5V regulator cut the following track
1)Start with the SMD chip MCP2200 Dispense a little bit of flux paste on the pads. Use an alligator clip to hold it in place. Solder 2 opposites corner pin and remove the alligator clip to proceed with the other pins
-
solder the resistors & the 6 diodes
-
Solder the ceramic capacitors
-
Add the IC Support
-
Add the crystals & the resettable fuse
-
Add the headers If you have a 5v bus add the 16 pins header
If you don’t have a 5v bus add the 10 pins header
- Add the Electrolytic 10uf capacitor
8)5V hack If you don’t have the 5V bus you should add the 5v 78L05 regulator
Bend the input pin to the 12V pin. Solder the output (5v) in place
Get a wire to reach the closet Gnd and connect it to the Gnd of the regulator
Do not solder the pots, the usb & the jacks yet !
Final Assembly place pots & jacks without soldering trim the pot (keep 5mm of stripes)
place the usb connector on the pcb (remark : ) screw the jacks & pots in place make sure everything is well aligned before soldering the pots & jacks
Avr tool chain On Mac download the latest Crosspack for AVR http://www.obdev.at/products/crosspack/download.html On Windows ...
Programmer I use the usbtiny programmer via avrdude in the terminal : connect your programmer to the isp port
set the fuses low_fuses=0xff high_fuses=0xde extended_fuses=0x05
this can be done via the following command : avrdude -c usbtiny -p m328p -qq -U hfuse:w:0xDE:m -U lfuse:w:0xFF:m -U efuse:w:0x05:m
bootloader
& upload an Arduino bootloader I use : optiboot_atmega328.hex
avrdude -c usbtiny -p m328p -F -U /Users/path to the file/optiboot_atmega328.hex
you can also use Avrfuses as interface to avrdude
Upload sketches Under windows you need to install the MCP2200 driver and have fun !
