These are suitable for DIY projects and the Raspberry Pi pcb as the screw outside diameter is only 2.5mm that fits in the Pi mounting holes.
Brass standoffs are essential components in electronic projects, particularly in applications where circuit boards need to be securely mounted within an enclosure or chassis.
Here's how they are typically used:
Board Mounting: Brass standoffs are used to elevate and secure printed circuit boards (PCBs) within an electronic enclosure or chassis. They provide a stable platform for the PCB, preventing it from coming into contact with conductive surfaces that could cause short circuits.
Mechanical Support: Standoffs act as spacers between the PCB and the mounting surface, ensuring proper ventilation and preventing heat buildup. This is crucial for maintaining the integrity of sensitive electronic components.
Isolation: Brass standoffs help to electrically isolate the PCB from the chassis or enclosure. This isolation is essential for preventing electrical interference, reducing the risk of noise and signal degradation, and enhancing overall circuit performance.
Easy Access: Standoffs facilitate easy access to the PCB for maintenance, repairs, or upgrades. By raising the board above the mounting surface, technicians can easily reach components and make necessary adjustments without disassembling the entire system.
Vibration Dampening: In applications where vibration is a concern, brass standoffs can help dampen vibrations transmitted to the PCB, thereby reducing the risk of component failure or solder joint fatigue over time.
Grounding: Depending on the design, brass standoffs can also be used as grounding points for the PCB. By connecting the standoffs to the ground plane on the PCB, they provide a convenient and reliable grounding solution.
Overall, brass standoffs play a crucial role in ensuring the structural integrity, electrical isolation, and proper functioning of electronic systems. Their versatility and reliability make them indispensable components in a wide range of electronic projects.

These HUB75 style panels are normally used to make video walls, you can sometimes see them on the sides of buses and bus stops displaying animations or short video clips. They have bright RGB LEDs arranged in a 32x32, 32x64 or 64x64 grid on the front. On the back there is a PCB with a set of dual IDC connectors (one input, one output) and 12 16-bit latches that allow you to drive the display with a 1:16 scan rate.
These panels require 13 digital pins (6 bit data, 7 bit control) and a good 5V supply, up to 4A per panel). They are 'chainable' if you connect one output to the next input - you will need a microcontroller with a suitably high speed processor and enough RAM plus a software library that supports this.
These displays are designed to be driven by FPGAs or other high speed processors: they do not have built in PWM control of any kind. Instead, you're supposed to redraw the screen over and over to 'manually' PWM the whole thing. On a 16 MHz Arduino, it's possible to squeeze 12-bit color (4096 colors) with 40% CPU usage but they will do best powered by an FPGA or other high speed multi-core controller (like a recent Raspberry Pi or Feather). They are pre-white balanced with nice uniformity so if you turn on all the LEDs it's not a particularly tinted white.
Here are some nice, tidy ways to connect up and drive your LED matrices:
- Interstate 75 (RP2040 based all-in-one controller)
- RGB Matrix Shield (for Arduino and compatibles)
- RGB Matrix Bonnet or RGB Matrix HAT (for Raspberry Pi)
- RGB Matrix Featherwing (for M0, M4 and RP2040 Feathers or nRF52840 Feathers)
