2024年10月28日 · It's a very basic schematic, I'm just doing the prototype for the power circuitry for 4AA batteriee pack now and fixing the overall pcb layout by making the circuit more efficient. I have gathered all the necessary components and created a basic outline in Altium, I’m very new to PCB design and I'm finding some aspects challenging.

2025年1月22日 · I’ve designed a PCB in KiCAD for the first time for a 220V AC application, and I’d love to get your feedback on its safety, reliability, and general design practices. Below are the details of the board and its key design elements: PCB Design Details. Board Dimensions: Board size: 82mm x 128mm. Material: FR4, 1.6mm thick. Layer Stack:

2020年11月17日 · Be prepared to spend some money, and also take some lessons in PCB design , especially the ones concerning signal integrity and controlled impedance, differential pairs, USB, etc. At a beginner lever, I wouldn't touch DDR. In fact, I'm aiming to design my own motherboard myself, using an SP7021-IF from SunPlus (search for Tibbo or Plus1).

2022年11月12日 · It is difficult to DIY a fine line PCB and you are more likely to use a PCB shop to manufacture the board. Unless it is a very complex layout most circuits can be laid out on a double sided PCB. The important rules to follow would be to pay attention to power rails, supply and ground, and make provision for 100nF ceramic chip capacitors.

2024年12月15日 · The PCB layout in post #12 is a total disaster!!! There are textbooks fill of circuit drawings and many of them are intentionally made easy to follow. There is a website, "Schematics for free" that has thousands of circuits that you can study for style and arrangement.

6 天之前 · The PCB works for a few hours from the battery but then stops. However, when I supply 3.3V directly to the ESP32 through the pins (for sketch uploading), it works (receives and sends data, and the seven-segment indicator works as well, though the motor and relay don’t activate due to insufficient current).

2019年6月9日 · Based on the very rough description you've provided, I'd SWAG this at between $1600-$3500 (US) for PCB design, software design, testing and manufacture for 12 prototypes, and anywhere from 1 month to 3 months, depending on how well you define what you want done, or if there is creeping featurism involved.

2024年5月15日 · Which software could design the text menu and graphics menu through the USB/RS232(PC) to control the ARM chip? Suggestions for schematic/PCB design software for hobbyists: Hardware design, software developing or AI: Portability in Software Design: Is there any software I may use to simulate a circuit design with gas sensor?
