Mini Drone PCB Case Study: How JLCPCB Solved High-Density SMT and Double-Sided PCBA Challenges

In the rapidly advancing field of unmanned aerial vehicles (UAVs), the engineering challenge has shifted. The market no longer demands just smaller and lighter drones; it demands smaller, lighter, and smarter systems. This establishes an important engineering paradox - how do you put cutting-edge capabilities such as AI-driven flight, high-definition video, and adequate data logging onto a PCB that must be small enough to meet weight and cost limits? This case study overviews how one embedded systems ......

JLCPCB helps simulate rockets to realize precise flight control!

Beepy is a flight computer specially designed for model rockets. The model rocket is very small in size, but the amount of computation required to achieve its flight is considerable. Beepy differs from traditional flight computers in that it adopts a design where multiple circular PCBS are stacked and connected, and uses ribbon cables to link each module together. This design significantly reduces the space occupied by the flight computer, enabling the device to maintain powerful functions while keepi......

High-Quality Small Batch Guitar Effect Pedal PCBs with JLCPCB Manufacturing

Fuzz Fields is an innovative guitar effect pedal that combines three modulated sounds to offer dynamically controlled fuzzy sound effects. Unlike traditional static pedals, Fuzz Fields can adjust the timbre in real time based on the dynamic input of the performer, achieving various effects such as "screaming", "swelling", "saturation" and "trembling". Its core feature is an inbuilt oscillator that can be modulated through external control, making it suitable for scenarios such as guitar tone explorati......
