MS-DIP/QFP1 PCB, for SMD QFP44-QFP64 with 1.0mm raster

16-channel GPIO expander with an I2C interface microcontroller can interface with 16 fully configurable digital input/output pins. It can produce PWM signals, so you can dim LEDs. It can be set to blink or even breathe pins at varying rates. With a built-in keypad engine, it can interface with up to 64 buttons set up in an 8x8 matrix. BOB-13601

Desoldering braid YT-82532 is a service tool for removing excess solder from solder pads. The braided structure of copper strands effectively absorbs molten solder, making it easier to clean PCB traces and prepare the surface for re-soldering. It is used in repair and assembly work on electronic circuits.

MS-DIP/QFP10 PCB, for SMD QFP48-QFP144 with 0.5mm raster

The ACS71240 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 120 kHz) and low conduction resistance (0.6 mΩ), it minimizes energy loss and offers a fast response time of less than 5 µs. Pololu 5240

The Digilent Servo Mounting Bracket Set (240-038) provides a durable and elegant solution for mounting servomechanisms in robotic projects. Its high-strength steel construction ensures stable mounting and long-term durability in demanding applications.
