Two development boards based on the @EspressifSystem ESP32-S31 dual-core RISC-V MCU with GbE, WiFi 6, Bluetooth, and 802.15.4.
https://t.co/f6tABCev7G

The ESP32-S31-Function-CoreBoard-1 development board is based on the ESP32-S31-WROOM-3 wireless module, and offers Gigabit Ethernet, USB 2.0 OTG, and onboard audio peripherals for connected IoT applications.

The ESP32-S31-Korvo-1 is a multimedia-focused development board based on the same ESP32-S31-WROOM-3 module, but featuring a dual-microphone array for speech recognition and near/far-field wake-up, two speaker connectors, a 4.3-inch LCD, a 3MP camera module, and a microSD card slot. It targets low-cost, low-power, connected audio/video and HMI applications.

People often think of SDRs as USB devices.
But SDRs come in many forms: USB, Ethernet, PCIe, and even old-school soundcard based designs.
Different interfaces, same idea: get RF samples into software.
Here are four examples:

Out with the old, in with the new. Replacing my custom EMFI platform with a #ChipShover!

Building smarter motion control?

This wireless stepper motor controller combines ESP32 + TMC2240 for precise control with real-time feedback—accessible through a simple web interface.

Great for robotics, CNC, and automation projects.

如果你是敏感单位，你拿ChatGPT写周报，那就是泄密啊。🤣。
理论上来讲，敏感单位确实不能用外部的AI系统的。

你任何像GPT/claude 提交的信息，你就假设全部交出去了。保证你数据privacy的只有他们的那个privacy policy，而已。

@mtrainier2020 @sqlist221311 用efues售后每年要亏20%的利润起码。要换se或者带有hsm的芯片他们不舍得。这种其实就是故意的。因为要考试售后成本和退货换壳转卖。在汽车行业也一样。tesla的18个ecu除了气囊edr几乎都没有关闭jtag

[Rainier @mtrainier2020]

这个是旧闻了。
2025年的defcon 论文。
大华摄像头的漏洞。
非常草台班子，大华把 firmware的key 直接hard code在代码里面了。
而且有两个RCE 漏洞。

[usIx @usix_ming]

@mtrainier2020 mqtt配置问题？

[Rainier @mtrainier2020]

这东西还是要靠民企。国企还是不太行。
国内最早搞这种无人机的是爱生集团。可惜爱生集团不太行。根本打不过民企。

[Rainier @mtrainier2020]

天上配个无人机作为侦察，给你提供坐标。下面放个几台这种装甲改装的自爆无人车，你怎么打？
而且可以做到完全AI识别，AI指挥，AI执行。
这些设备上面都要跑AI模型，你说跑本地的模型，还是跑远程的模型？
