 ===== Needed Parts and PCB =====
-You need a **PCB**. You may use the layout from [[https://github.com/breaker27/smarthomatic/tree/master/hardware/generic_maxi_speed_1|Github]] and etch it yourself or [[https://www.smarthomatic.com/shop/|order]] the PCB or a complete kit.

 The base station is designed to run 24/7 on 5V and to be connected to a PC, so you may prefer a stabilized 5V power supply, and not running on batteries. Any USB power supply will do well, and many mobile phone chargers are working at 5V.

   * **ATMega:** Before inserting it, you may want to check the voltage levels when switching the power on. Pin7 should have VCC (5V) against pin8 (ground). If you have different voltages: don't panic, nothing is broken, nothing is fried. Search your error. To insert the ATMega, bend the pins at 90 degreed by placing the ATMega on the table and bending it carefully. Then insert it into the IC holder. Be sure that you are not charged with electricity (ESD!) when touching the IC pins.
   * **RFM12B:** You should also check the voltages first before soldering the module. At the place for the radio module the pad beside the antenna and at the opposite side the third pad should read about 3.3V. For soldering, read [[rfm12b_soldering|the RFM12B mounting instructions]].
+  * **Antenna:** After you solder the antenna, which might be a little bit longer at first, measure it's length and cut it exactly at 82.2mm.
