Understanding ESP32/8266 Interfaces: Your Key to Building Smart Home IoT Projects
Introduction
The ESP32 and ESP8266 are among the most popular IoT development boards on the market today, featuring powerful WiFi and Bluetooth capabilities, along with a rich set of interfaces to meet various IoT application needs. This article will detail the interfaces available on the ESP32/8266 and what they can be used for.
GPIO Interface
The GPIO (General Purpose Input/Output) interface is one of the most basic interfaces on the ESP32/8266, used to control the state of external devices. These interfaces can be

The New Combination of RISC-V and FPGA — BeagleV-Fire
Recently discovered an interesting development board that is based on RISC-V and FPGA.
This form is my first encounter.
It is the
BeagleV®-Fire
BeagleV®-Fire adopts Microchip's PolarFire® FCVG484E 5-core RISC-V system-on-chip and FPGA architecture.
It has 4 64-bit RV64GC application cores and 1 64-bit RV64IMAC monitor/boot core, with a performance of 3.125 CoreMarks/MHz and 1.714 DMIPS/MHz.
The FPGA part has 23,000 logic elements (4-input LUT + DFF), 68 math blocks (18x18 MACC), and four 12.7Gbps SerDes
Common Commands for ARM Development Boards
1、reboot means to restart.
2、source makes the modified files take effect immediately, avoiding the problem of having to restart for the changes to take effect. For example, if we modify /etc/profile, the changes will not take effect immediately. In this case, we can enter source /etc/profile to apply the changes.
There will be more updates in the future.
3、chmod -R 777 /home/edu/practice sets all file permissions in the practice folder to 777.
4、Compress a single file: gzip

Industrial IoT Gateway Development Board – Mill RZ/G2UL
Last time I introduced the Remi Pi launched by Mill, priced at only 198.
This time we will look at another new product from Mill, which also uses a Renesas chip. However, the core board is cheaper.
It is based on Renesas's RZ/G2UL, featuring an ARM Cortex-A55 core with a frequency of up to 1GHz, and a Cortex-M33 MCU core with a frequency of up to 200MHz.
However, there is no GPU, yes, no
