<\/a><\/p>\nThere are 4 areas that the Tinusaur board could be divided to: A1, A2, A3, A4.<\/p>\n
Assembling<\/h1>\n
Here is the recommended order of soldering the parts:<\/p>\n
- \n
- MCU socket. Note: do not insert the chip yet.<\/li>\n
- Capacitors C1, C2 and resistor R1.<\/li>\n
- Headers H1, H2.<\/li>\n
- External power header \u2013 red.
\nBattery on\/off header \u2013 yellow.<\/li>\n - ISP header.<\/li>\n
- Battery holder.<\/li>\n
- RESET button.<\/li>\n<\/ol>\n
The battery holder and the battery are optional but if you decided to put them on make sure you solder the battery holder before<\/i> the RESET button.<\/p>\n
IMPORTANT<\/span>:<\/b><\/p>\n
External power header (JP1, red, the one closer to the 8-pin header H1) is to connect external power. DO NOT put a jumper there \u2013 that could damage the board.<\/p>\n
Battery On\/Of header (JP2, yellow, the one closer to the mount hole) is to connect\/disconnect battery to\/from the board. DO NOT have this on<\/b> while the board is connected to the programmer or external power source \u2013 there is no circuit to protect the battery from overcharging.<\/p>\n
If you’re not going to use an external power source or the battery on the board don’t put any jumper on at all.<\/p>\n

Note (about <\/i>external power source<\/b><\/i>): If you’re going to use external power source (JP1, red in color, the one close to the 8-pin header H1) make sure you connect the negative pole (-) to the outer pin of the header and positive (+) to the inner one.<\/p>\n
Note (about <\/i>battery placement<\/b><\/i>): If you’re going to use the battery in the holder make sure you insert it correctly \u2013 that is to have the negative (-) downwards (facing the holder) and the positive (+) (the side with the text markings) upwards.<\/p>\n
