Pi 4 And Half Breadboard Prototyping Base
This 145 x 96 mm prototyping base holds a Raspberry Pi 4B/3B+ on four standoffs at its 58 x 49 mm M2.5 hole pattern. The Pi's GPIO edge faces an L-fenced pad, where you stick down any adhesive-backed half breadboard (about 83 x 55 mm). It also has a vented window under the board and a zip-tie anchor block, so a tug on the USB-C or HDMI cable doesn't rip jumpers out of the board.
Breadboard Angle Stand With Tray
A 20° angled stand that tilts a solderless breadboard toward you for better wiring visibility, with a 163 x 25 x 7 mm parts trough in front for resistors and jumpers. The 172 mm wide deck takes a full-size 830-point board or two half-size boards, held by a 4 mm front lip and an 8 mm rear backstop with three 14 mm notches for jumper bundles; two M3 clearance tabs let you screw it to the bench. Overall 172 x 108 x 38 mm, open-ribbed underneath so it prints without supports.
