This is a larger, 20-volt drill, but it shares all of the most important characteristics of the smaller, 12-volt DeWalt: It’s very powerful and extremely comfortable to hold and use, and the little convenience features, such as the belt hook and the case, are spot-on. If you take on projects that require drilling lots of holes and sinking long screws, we recommend stepping up to the DeWalt DCD791D2 20V Max XR Li-Ion Brushless Compact Drill/Driver Kit. The DCD701F2 also comes with a nice belt hook, and the battery gauge is on each battery rather than on the tool, so you can check batteries without having to insert them into the drill. The battery is designed so that the drill can stand upright when not in use (other drills, like the runner-up Bosch, need to be placed on their side), and the LED is positioned such that it illuminates the drill front better than most. The molded handle seems to account for every curve and bulge of the hand, making this drill the most comfortable we’ve ever held. The DeWalt 12-volt’s power is on a par with that of some of the other drills we looked at, but it particularly excels in ergonomics and convenience features. In our tests, it bored 30 1-inch holes through a 2-by-10 on a single battery charge-results that show it can handle just about anything within the four walls of a home, and even the occasional foray into more aggressive work such as a small decking repair.

This is just to give an idea on how to interface them.The DeWalt DCD701F2 12-volt drill combines power, comfort, and convenience in a way that none of the other tested drills do.

The code will spin up the selected motor with a given speed. How to find and fix a fault on this BL-Ctrl you can see here: TroubleshootingĬontrolling the BL-Ctrl with own hardware is easy.Ī sample code for nearly any AVR is given below. If the BL-Ctrl have a fault, you can see this e.g. The base resistors R3, R6 and R9 need to be changed through a low-resistance resistor, i.e. Please note: In version 1.2 for T1-3 the part PDTC143 with integrated base resistor is used. That is necessary because the switch is not designed for those current and starting flashes coming with the high voltage. Here you need to adjust the wirering in that way that the BL-Ctrl are hooked up directly to the power supply and not over the switch of the Flight-Ctrl. It is also possible and the same as with the BL-Ctrl V.1.1 to fly the MK with four-cell !Lipo's.

The controller is still sensitive to moisture and should be shrink wrapped with shrink tubing! For details see also BrushlessCtrl and water landing. It is advisable to bend the capacitor by 90° so that it fit parallel to the outer side of the board.įurther you can see on the picture how to connect the I2C-Bus-Wires and the power supply. On the pre-assembled BL-Ctrl V1.2 you need to solder the enclosed Elko: Here you can see the addresses and positions of the motor controls and also the direction of rotation of the assigned propeller:ĭepending how many motors you will use on your copter you need for the upper addresses of the BL-Ctrl's a different software.

On the V1.2 the motor address is set by a solder jumper on the board. See also the version history Ctrl_History. Transistors T1, T2, T3 are replaced now by transistors with built-in resistors.Better heat dissipation of the FET's and the Shunts.
