这是一位工程师基于硬禾学堂"暑期一起练"的ESP32-S2平台实现的网络收音机、FM收音机的功能，项目开源在电子森林的项目页面（点击左下角的“阅读原文”）。 可以通过WiFi接收网络上的电台，也可以通过FM模块接收空中的电台，并可以通过按键进行切换、选台 ...

Waveshare 近期推出了一款专为驱动DDSM400 轮毂电机而设计的紧凑型 Raspberry Pi DDSM（直驱伺服电机）电机驱动器——DDSM Driver HAT (B)。 树莓派 HAT（Hardware Attached on Top）是一种专为树莓派设计的附加板，通过标准化的物理和电气接口来增强树莓派的功能。 直驱 ...

虽然现实世界中，我们并不能施展魔法，但对工程师来说，PCB和各种半导体器件就是我们的魔杖。 从成品上来看，这顶巫师帽非常类似《哈利·波特与魔法石》中的分院帽，而它也不仅仅是像而已，这顶巫师帽不仅拥有一张可以开口说话的嘴巴，还有一只灵动的 ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...

D0WD, a low-cost alternative to LilyGo T-Display, lets you mirror your desktop monitor over Wi-Fi with an ESP32 ...

When working on a project, plenty of us will reach for an Atmel microcontroller because of the widespread prevalence of the Arduino platform. A few hackers would opt for a bit more modern part like an ...

Not every DIY project needs a Raspberry Pi ...

Open-hardware platforms enable rapid prototyping and faster time-to-market of new IoT applications. The objective of this post is to give a brief introduction to another open-hardware IoT playground — ...

My first foray into the IoT utilized the Espressif ESP8266, an SoC with 32-bit MCU and 2.4-GHz Wi-Fi built in. Since then, I have used many different module variants based on the microcontroller. So ...
