| DIP uncommitted | Similar to a solderless breadboard in layout, this board has space for 0.3", as well as 0.6" wide DIPs. Sites for two capacitors (the 0805 site could also be used for a resistor) are on the bottom. | Use to add in any 0.3" DIP-packaged component to your circuit, including such devices as DIP switches. End to end stacking can accommodate longer than 20-pin packages. |
| SOIC uncommitted | Mount a SOIC (0.025" lead pitch), up to 28-pins, on one side, or mount up to 3 SOT-23 packages, with up to 6 pins each, on the other side. WIthy careful planning many useful combinations of SOICs and SOT-23s can be accommodated as well by using both sides at the same time. | Any IC which is in a 28 pin or smaller 0.3" width SO package, and/or 3/4/5/6 pin SOT-23s, and/or some 2-lead discretes (0402, 0603 and 0805 sizes). |
| SOT-23 uncommitted | 4 independant SOT-23 sites, each site has a position for a bias resistor at each terminal. Each resistor site is an 0805 SMD in parallel with an 1/8 W through hole. | Mounts up to 4 SOT-23 3 pin devices such as bipolar transitors, FETs, diodes, regulator ICs, etc. |
| 2mm to 0.1" transition | A dual row of 2 mm-spaced pads wired directly to 2 rows of 0.1 inch pads. Two of the boards can be used side-by-side to extend to as large as a 2×20 connector. | Good for mounting salvaged metric components, including 2 mm pitch connectors. |
| SOT-223 uncommitted | Allows the use of (medium size) SOT-223 packaged devices. | Mounts up to 2 SOT-223 4-pin devices such as bipolar transitors, FETs, diodes, regulator ICs, etc. |
| LQFP-64 | Use with a 10 mm square body, 0.5 mm lead pitch LQFP package. | Connect to a chip such as one of the 64-LQFP PICs. |
| LQFP-100 | A 0.40 mm-pitch, 100 pin Quad Flat Pack board. | Connect to a chip such as one of the 100-LQFP PICs. |
| Name | Description | Applications |
| 7-pin vacuum tube | A PCB which holds a ceramic 7-pin tube socket. Some tubes which use this base are: 6AU6, 12AU6, 12AJ6, 12AL5, 12AQ5, 12AS5, 12AT6 | Any circuit that needs a tube/valve of this base. |
| 9-pin vacuum tube | A PCB which holds a ceramic 9-pin tube socket. Some tubes which use this base are: | Any circuit that needs a tube/valve of this base. |
| Octal tube | Any circuit that needs a tube/valve with this base. | |
