Sự cố EMI chủ yếu do bố trí PCB, không phải lỗi firmware! Thiết kế bo mạch quyết định việc tín hiệu có bức xạ hay không. Ví dụ:
- Đường mạch dài trở thành ăng-ten hiệu quả ở tần số cao
- Khe hở lớp tham chiếu tạo vòng bức xạ
- Tụ giải ghép đặt xa IC phản tác dụng

Giảm tốc xung hay bật trải phổ chỉ che giấu vấn đề. Giải pháp: Ưu tiên kiểm tra đường truyền, đường trở về, và bố trí linh kiện trước khi chỉnh firmware.

I've been a little nerdier than normal this past month, working on my first Arduino project.

This thing is making me create my own custom PCBs, code in a language I've not delved in much, and struggle with the basics of "low level" menuing with buttons.

But it's been fun, and it's working!

A simulated Arduino circuit with an LCD, some buttons, a toggle switch, and a potentiometerA custom Arduino breakout board. The pins on the Arduino are traced to different connectors on the board for connection to other boards.A circuit board with lots of components on it. In the upper-left is a basic DC Voltage regulator to verify the correct voltage through the board. On the right is an LCD screen that uses a connector to send the information to the Arduino breakout board.

Below the Voltage Regulation area is a photoresistor connected to a transistor, which also is routed to the Arduino breakout board.A circuit board with space for surface mount button switches. There are four in a diamond pattern for up - down - left - right, and two below the patter for enter and back.

They use a connector to talk to the Arduino board.

My company is #hiring a Senior #HardwareEngineer. We're a series B startup making fully autonomous survey drones.

Looking for 4+ yr exp in robotics/mechatronics/mech.eng., Solidworks, 3D printing, basic C/C++/py skills, etc. You'll do a mix of designing/implementing projects and leading junior engineers.

$125k + equity/benefits. US employment elig. req'd; role is in-person in #Philadelphia (we're flexible w/ WFH, but HW work is gonna be mostly on-site).

DM for details! #FediHire #HachyJobs
