![]() ![]() The 5V input’s large capacitance combined with the cable also provides an interesting RC filter between this distribution board and the regulator. Power quality is essential to me in this project, so there’s no such thing as too much filtering! As mentioned earlier, this project has a lot of filtering. The double ESD protection will handle the ESD event in a high altitude, low humidity setting such as Denver, CO, or Calgary, AB present.Īs you might expect from a power distribution board, the schematics are fairly simple, but still contain more components than just the connectors. These are tiny but automotive qualified and likely to be capable of handling ESD events at sea level in mid to high humidity conditions. ![]() I’m using the same 0402 size TVS diodes for the 5v lines that I used on the main power board-the TI TPD1E10B06QDPYRQ1. By having ESD protection on the inputs as well as on the regulator board, we should have a fairly high degree of protection for the camera. If you are kneeling on a carpeted floor, like many trade show venues have, building up a static charge as you are getting the camera ready plugging in devices presents a very easy way for an ESD event to damage a fairly expensive piece of equipment. ![]() In addition to the power filtering, I’m also adding some basic ESD protection to each input. The filtering on the front power distribution panel we are building in this article is to protect each plugged-in device from the possibility of receiving or transmitting conducted noise. The main regulator’s filter is to protect the camera from electrical noise being conducted back to it and potentially interfere with the audio or even video recording. While the power from the camera is filtered on the main unit, I also want to have filtering on the front distribution board. I plan to have a couple of extra power outputs available for future usage, perhaps for powering a light, a recorder, or another device that I haven’t yet added to my setup. The motor, however, is very electrically noisy, so it needs good isolation. Out of these, only the SDI to HDMI convert needs remotely clean power. The main loads are the hefty 5V Tilta nano focus motor, 5V SDI to HDMI converter, 5V Tilta follows focus control, and the battery voltage powered monitor. This board has several loads on it, but it is purely a distribution board with no regulation. You can also find the main power supply board, which this board will plug into on GitHub as well. You’ll find all the components for the board in my open source Celestial Altium Library. As always, you can find this project on GitHub under the MIT license, so you can make your own or take portions of the schematic for your own projects. ![]() However, I had some requests for a followup on the front distribution board. In the previous article, I wasn’t sure if I was going to write about this board and section of the project or put it up on GitHub. Therefore, I’m making a board that can be mounted on the shoulder pad’s front rails that will provide power distribution and further filtering. My shoulder rig for the camera has several fixed loads, which I don’t want to have to unplug individually when I take the camera off the shoulder rig. It features isolated 5V power supplies for the radio microphones and extensive power filtering to ensure the highest quality power throughout the system.
