8
+The Nufront NL6621M is a highly integrated SoC designed for low-cost, high-throughput WLAN products. It integrates an MCU, MAC, 1T1R baseband and an RF transceiver with an on-chip power amplifier into a single chip. The NL6621M supports 802.11b/g/n, Wi‑Fi Direct (SDIO network card mode), BSS STA, soft AP and Wi‑Fi Protected Setup. It also supports WMM‑PS and WPA/WPA2 security protocols.
9
+
10
+The NL6621M can operate as a slave device controlled by a host processor or as a standalone WLAN device that does not require any external processor. Supported peripheral interfaces include Quad‑SPI, standard SPI, I2C, UART, GPIO, I2S audio, and PWM audio. The chip can connect directly to peripherals such as speakers, cameras, flash memory and LCDs. A full TCP/IP stack (UDP, HTTP, etc.) is integrated on the device. High-performance wireless transport combined with rich I/O and protocol support makes the NL6621M a strong single‑chip solution for wireless audio, wireless video, smart home, and medical IoT applications.

18
+
19
+该传感器模块对环境光线适应能力强，其具有一对红外线发射与接收管，发射管发射出一定频率的红外线，当检测方向遇到障碍物（反射面）时，红外线反射回来被接收管接收，经过比较器电路处理之后，绿色指示灯会亮起，同时信号输出接口输出数字信号（一个低电平信号），可通过电位器科比电子旋钮调节检测距离，有效距离范围2～30cm，工作电压为3.3V-5V。
20
+
21
+该传感器的探测距离可以通过电位器调节、具有干扰小、便于装配使用方便等特点，可以广泛应用于机器人避障、避障小车、流水线计数及黑白线循迹等众多场合。

-- Infrared (IR) sensor — detects reflected IR light
53
-- Ultrasonic sensor — measures sound wave echoes
54
-- LIDAR sensor — uses laser light to detect distance
55
-- Radar sensor — uses radio waves

+- `DIY an output adjustable vehicle power supply`, only need access to your 12V power input, the output voltage can (14-35V) continuously adjust, but the output voltage can not be lower than the input voltage.

+- `Primary front level system power supply`, when you do a project at the time of 10-18V input when the system board and you need to supply 24V and about its great power, with ordinary DC-DC module power is too small , then you choose this module we will be your best choice, do not debug directly on the machine to work, easy to do and efficient power boost.
