Crowbits Master Kit Tutorial - Part 2: ESP32 intrusion scanner and visual programming - CNX Software - Embedded Systems News
I started Crowbits Master Kit review last month by checking out the content, user manual, and some of the possible projects for the ESP32 educational kit including a 2G phone and a portable game console.
For the second part of the review, I’ll go through one of the lessons in detail, namely the intrusion scanner to show the whole process and how well (or not) it works.
Let’s go to Lesson 5 directly, although I’d recommend going through the first lessons that provide details about the hardware and visual programming basics using Letscode program, which is basically a custom version of Scratch for Crowbits

ESP32-C6 WiFI 6 and Bluetooth 5 LE RISC-V SoC for IoT devices coming soon - CNX Software - Embedded Systems News
Espressif Systems introduced their first RISC-V wireless SoC last year with ESP32-C3 single-core 32-bit RISC-V SoC offering both 2.4GHz WiFi 4 and Bluetooth 5.0 LE connectivity, and while the company sent some engineering samples of ESP32-C3 boards months ago, general availability of ESP32-C3-DevKitM-1 and modules is expected shortly.
But the company did not stop here, and just announced their second RISC-V processor with ESP32-C6 single-core 32-bit RISC-V microcontroller clocked at up to 160 MHz with both 2.4 GHz WiFi 6 (802.11ax) and Bluetooth 5 LE connectivity.
