Macros for later use can be created by yourself. In the window located to the right of the board size selection window there is a window called macros, in it we can select ready-made macros consisting of a graphic image of the part on the silk-screen layer on the back of the board and part conclusions on the print layer. If we need to establish contact without a hole for the SMD output, select SMD - contact. To draw a track or set a piglet under the output, click on the pictograms with the symbol Conductor and Contact. You can draw a printed circuit board by combining ready-made parts in the form of macros with a path, or in the simplest case, individual pigments not connected to a macro. In the following figure, the board dimensions (width and height) in millimeters are set in the violet window. In the central part, on a dark background with a grid, the created printed circuit board is placed. After starting it, we see the following program window: Moreover, all of them are not too different by the principle of work.
The last version of the program was released sixth, and we will consider it in more detail.
There are both ordinary requiring installation, and portable ( Portable) version of the program.
The most widespread in amateur radio practice was the program for manual wiring of printed circuit boards sprint layout. There are special programs for PCB layout, both in manual and semi-automatic mode, with subsequent output either to print to a printer or to a file for printed circuit boards. In extreme cases, you can draw a picture on a printed circuit board with a regular permanent marker in several layers, but this method, due to the possibility of ghosting, is less preferable than the LUT method. The cost of such a marker in radio stores is about 55 rubles. There are different ways of transferring the protective track from the etching solution to the printed circuit board pattern, the most common are the LUT (laser-ironing technology) method and drawing the picture with a special marker for printed circuit boards. In electronic technology, for these purposes, printed wiring is used, which is obtained by unprotected, specially applied protective layer, a layer of copper foil.Īs a result, from a piece of fiberglass with a glued layer of copper foil, which is called foiled fiberglass, after etching, a printed circuit board is obtained. To connect together parts of electrical equipment, such as a machine tool in production, wires and cables are used. I see that DSC60xx family supports dual-clock choice, so it could be possible to use a DSC6023 with two MHz choices ? Smaller and well stocked looks to be DSC6001HI1A-005.0000T. see also for talk around the slew options, and radiation effects. If you are just going board-board, 2mm or even 1mm pin sticks can take up less area.Īddit: for a proven oscillator (used in FLiP), Digikey stock the SIT8918BE L13-33E-5.000000 2.5x2.0mm
You can get oscillator modules, 5MHz ~ 6.5MHz that come as small as 2.0 x 1.6mm, or even (1.54mm x 0.84mm) ! if you can work BGA packages I think the QFN package is tagged EOL - will that be an issue ? One new thing I'm trying out is using a milled out piece of acrylic to give a hole on the back of the servo for mechanical support, turning it into a "robot servo".
Top board has QFN Prop, eeprom, 3.3 v regulator, crystal, accelerometer, and prop plug port.īottom board has the motor driver h-bridge, transistors and resistors and soon a big capacitor. This is all too much to fit on one PCB of same size as the one in this HXT12K servo.īut, there's plenty of room under the board. So, I'm gearing up to take another stab at this.Ĭurrent plan is to also add in a 3-axis accelerometer and a WS2812B in there. I went down this path before, but found I didn't have the skill set or the tools to do it: īut now, I've learned Eagle, so I can make circuit boards thin enough to fit and my PCB design skills have improved.Īlso, I have a Shapeoko CNC router so can mill the boards myself. The control wire will now be a 1-wire communication bus with bidirectional coms. I'm finally getting close to having a Prop powered hobby servo.
