-Module is equipped with AC/DC rectifier circuit and LDO voltage stabilizer (with low dropout) - external feeder with voltage stabilization is not needed.
+The module is equipped with a AC/DC rectifier circuit and a LDO voltage stabilizer (with low dropout) -an external feeder with voltage stabilization is not needed.
+The module can be powered with a step down transformer with an output voltage which is greater than 6 volts and lower than 15 volts. In order to reduce power losses it is recommended to use power supply between 6-9V.  The POWER LED signalizes a connected feed (“POWER” description on the board).
+All ATmega2561 signals are available on three connectors on the edge of the board. Connectors pin assignment is described in the next part of this instruction. It includes full descriptions of ATmega2561 pins and their alternative functions. The module is equipped with a microprocessor reset circuit (when power on) and a reset button for a microprocessor restart. A microprocessor can be programmed with an on-board JTAG programmer over USB or with an ISP interface.
+To the seventh pin of port B (named as PB7) the status LED (described as PB7 on the board) is connected. This LED can be used as a status indicator of application software. Low state on PB7 pin causes the status LED to be lit.
+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.

-===== Ühendamine =====
+===== Connecting =====
-Kontrollermooduli ühendamisel teiste moodulite ning seadmetega tuleb esmalt veenduda, et Kontrollermooduli toide ei ole ühendatud. Ajal kui plaat 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 (alla 500 mA) toiteks võib Kontrollermooduli ühendada ainult arvutiga kasutades mini USB kaablit. Kui kasutusel on moodulid, mis vajavad summaarselt rohkem voolu kui 500 mA tuleb seadmete toiteks kasutada eraldi toiteallikat. Kui Kontrollerplaadiga on ühendatud välise toiteallika pistik, lülitub moodul automaatselt USB toitelt välisele toitele.
+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 (less than 500mA) you must only connect the controller module with a PC using an USB port. If you are using modules that need to use a greater current than 500 mA, you must use a separate power source. If a controller module is connected to a separate power source, then the module automatically does not use USB a power supply.
