The 802.11bgn module is the best new device for connecting user equipment to the internet, supporting SSL and featuring robust performance. Makers looking to connect their Arduino Zero (or Uno) to the internet can now achieve this with Adafruit’s new ATWINC1500 wireless breakout board. The ATWINC1500 at the core of the breakout board is an … Read more
Recently, I found a few HC-12 wireless modules that I had bought a long time ago from my drawer. I intended to use them to create a wireless remote control for a small toy, but during testing, when I connected to the computer and sent data through the serial debugging tool, it froze, although receiving … Read more
Click the blue text above · Follow us A wireless module (RF module) refers to a module product that achieves data transmission through radio technology. The module integrates high-frequency components and has conventional interfaces (such as serial ports, SPI, digital signals, etc.), allowing users to develop wireless products without needing to master high-frequency knowledge or … Read more

315M Transmission Circuit Principles In a static state, 12V provides voltage to the collector of Q2 through L1, R1, and the base-emitter of Q1. When data arrives, Q2 turns on, causing the emitter of Q1 to be at 0 potential, which means Q1 is initially off. When the emitter of Q1 is at 0 potential, … Read more
We are making daily toothbrushes more convenient in a new way. With the increasing richness of people’s material lives, the proportion of food in daily social life is also rising, and various oral care issues are becoming more prevalent. The first step in oral care is “brushing teeth”. So, how do we choose a toothbrush? … Read more
