| - | Kontrollermoodul on varustatud alaldiga ja pingestabilisaatoriga. Sisendpingeks sobib plaadile 6-14~~SP~~V. Voolukadude minimeerimiseks on soovitatav kasutada 6-9 V pingeallikat. Toite ühendamisel peab plaadil toite LED põlema hakkama. Kui see ei sütti, võib põhjus olla puudulikus toites või hoopis lühises Kontrollermoodulil või temaga ühendatud seadmetes. Kontrollermoodul on varustatud kaitsmetega ja lubatud voolu ületamisel toiteahelates põleb kaitse läbi, kaitstes nii kallimaid komponente. Kaitsmeid saab vahetada, aga soovitav on seda teha kogenud elektroonikul, | + | [{{ : |
| - | Kontrollermoodul on varustatud oleku LED-iga, mis on ühendatud mikrokontrolleri viiguga PQ2. LED süttib, kui viik seada madalasse olekusse (loogiline 0). Seda on hea kasutada lihtsa indikaatorina. Samuti on ühendatud LED viiguga PQ0, kuid see on reserveeritud USB ühendusele ning selle programmiline juhtimine ei ole soovitatav. Viiku PQ1 on ühendatud läbi pingejaguri USB toitesignaal ning sealt viigust on võimalik lugeda, kas USB kaabel | + | The module is equipped with a LDO voltage stabilizer (with low dropout). The module can be powered with a step down transformer with an output voltage which is greater than 6 volts and lower than 14 volts. In order to reduce power losses it is recommended to use power supply between 6-9V. The power LED signalizes a connected feed. The power LED must be lit, when connecting to the power. If it does not illuminate, the cause may be an inadequate power supply or a short circuited Controller module or a short circuit in other connected devices. Controller is equipped with fuses. If overcurrent occurs, the fuse blow and protect the most expensive components. Fuses can be changed, but it is recommended to do an experienced electronics experts. Fuses are small SMD components, and the user is difficult to replace them. The microcontroller can be programmed over USB, through the bootloader. To enter the bootloader, press and hold the button S0 on the Controller module, and then reset the controller. |
| - | Plaadile on paigaldatud SD mälukaardi pesa kuhu on võimalik sisestada standardne mikro SD mälukaart. Mälukaart on ühendatud SPI liidese kaudu mikrokontrolleriga ja seda võib kasutada andmete salvestamiseks, juhul kui need peavad säilima ka pärast toite eemaldamist mikrokontrollerilt. | + | The Controller module is equipped with a status LED, which is connected to the microcontroller pin PQ2. The status LED will light up, if the pin is set to low (logical 0). It is good to use as a simple indicator. Another LED is connected to the pin PQ0, but it is reserved for the USB connection, and the programmatic management is not recommended. Pin PQ1 is connected through the voltage divider to USB power. This pin can be used to read, if the USB cable is connected to the Controller module or not. |
| + | The module is equipped with SD memory card slot, where it can be used as a standard microSD memory card. The memory card is connected to the microcontroller via the ISP interface and can be used to store data where data must be maintained even if the power supply is removed. | ||

| - | Kontrollermooduli ühendamisel teiste moodulite ning seadmetega tuleb esmalt veenduda, et Kontrollermooduli toide ei ole ühendatud. Ajal kui moodul on pingestatud, on ohtlik seadmeid ühendada. Mooduleid ja seadmeid tuleb omavahel ühendada ettevaatlikult ja liigset jõudu kasutamata. Vale käsitlemise korral võivad piikriba piigid kergesti kõveraks painduda. Programmeerimiseks ja nõrkvoolu | + | When connecting the controller module with other modules or devices, you must first make sure that the controller module power supply is not connected. Modules and devices must be connected to each other with care. It is important not to use excessive force, wrong handling may damage the module. For programming and to power with low currency |
