7.3 Using UC00A for loading program to Arduino Pro Mini
is a compact Arduino board and comes without on-board USB to UART
chip. User may use UC00A for loading program into Pro Mini. UC00A has the socket ready
(header socket) for user to easily plug into Arduino bootloader pin.
To load program, user need to extend the Arduino PRO Mini bootloader pin out. User may
use right angle or straight header pin. And user may solder from bottom or from top.
Figure below is an example of Arduino Pro Mini. Reset pad has a “GRN” label at the site,
indicating Green and GND pad has a “BLK” label at the site to indicate Black.
To connect UC00A to Arduino Pro Mini, user need to ensure that Green label from UC00A is
connect to “GRN” label of Arduino Pro Mini. And Black label from UC00A is connect to
“BLK” label of Arduino Pro Mini. Also please do make sure the TTL logic and power is
compatible with the Arduino Pro Mini as there are 5V and 3.3V version. UC00A Rev3.0
support both, but user must select the voltage from Vsel slide switch at ‘G’ in product layout
section. Default Vsel is 5V.
