The 9V 10W USB Step-Up Converter module converts 4.2-5.2V input voltage to 9V DC output voltage, with a maximum current of 2A and a conversion efficiency of 96%. The device can operate in a wide temperature range, from -40°C to 85°C, which makes it ideal for powering various electronic devices in harsh environments.

VisionSOM-8Mmini series module with NXP i.MX 8M mini processor (4x Cortex-A53 core @1.6GHz + 1x Cortex-M4 core @400MHz). It has 1GB of LPDDR4 RAM, 8GB of eMMC. SoMLabs SLS23X8MMQC_1600C_01GR_08GE_0SF_I

The module is based on the ESP8266EX chip. Thanks to the support of the 802.11 b/g/n standard, it enables wireless communication with WiFi networks, which allows for Internet access and data exchange. It is programmed via the USB Type-C connector using Arduino, MicroPython or NodeMCU. WeMos D1 Mini Type-C

The DC motor driver module enables the motor to be controlled using a PWM signal with several supply voltages (3V, 6V, 12V, 24V and 35V) and a maximum continuous current of 5A.
