| - | Every sensor on the board are connected through the jumper, enabling to select between on-board sensor or external sensor which can be connected to the same port on the CON2 connector. By default all on-board sensors are connected to the analogous inputs of the micro controller (ADC0-ADC3). In addition to on-board sensors, several analogous external sensors can be connected with sensor board through the connection CON2 to ports ADC4-ADC7. Attention have to be paid to the fact that the ATmega128 is using same ports (ADC4-ADC7) for JTAG programming. Both functions cannot be used concurrently. The micro controller have to be configured to use accordingly. However the external sensors are required they can be also connected to ports ADC0-ADC3, but appropriate jumpers have to be shifted. | + | Version 5.0 |

| - | ==== Low-pass filter ==== | + | ---- |
| - | Low-pass filter can be composed between analogous inputs 0-3 (PF0-PF3). Resistor and capacitor will be connected to the socket for building up the low-pass filter. By default a low-pass filter is composed for the channel 0 (PF0). resistor value is 10 kΩ and capacitor value is 100 nF. | + | Version 2 |

| - | Mooduli ühendamisel on soovitatav järgida allolevat järjekorda ja enne ühendamist veenduda, et Kontrollermooduli toide on lahti ühendatud. | + | |
| - | + | ||
| - | - Ühendada moodul Kontrollermooduliga (20 soonega ribakaabel). NB! Kontrolleriga ühendatakse pistikupesa, | + | |
| - | - Ühendada vajadusel infrapuna kaugusandur (must juhe - GND). | + | |
| - | - Ühendada vajadusel Digitaalmoodul ja LCD ekraan. | + | |
| - | - Ühendada vajadusel ultraheli kaugusandur (must juhe - GND). | + | |
