Electric tin soldering iron with adjustable temperature and LCD - 908S 80W

Wheels for 360 degree continuous rotation servo motors type SG90, FS90R, SG92r. The wheels have silicone tyres and measure 60 mm (2.36″) in diameter. Four additional mounting holes for 4-40 bolts allow the wheel to be used with several of our universal mounting bracket.

The first Raspberry microcontroller with the proprietary RP2040 chip and a dual-core Arm Cortex-M0+, the Foundation's cost-effective yet highly flexible solution. Designed for high performance and with a high degree of digital interfaces. Programming in C/ C++ and MicroPython.
