“Three Fives” 555SE Discrete Timer SMT Soldering Kit: The “555SE” Discrete 555 Timer Kit from Evil Mad Scientist Laboratories is a surface-mount soldering kit that lets you build a faithful and functional transistor-scale replica of the NE555 timer integrated circuit, one of the most classic, popular, and all-around useful chips of all time.
Like its larger sibling the “Three Fives” soldering kit, the 555SE is an easy soldering kit that results in a working 555 timer, styled like an integrated circuit. However, while the Three Fives kit is a traditional through-hole soldering kit styled like a “DIP” packaged (through-hole) integrated circuit, the 555SE is a surface mount soldering kit, styled to look like a smaller “SOIC” packaged (surface mount) integrated circuit.
SparkFun Qwiic or Stemma QT SHIM for Raspberry Pi / SBC: The SparkFun Qwiic or Stemma QT SHIM for Raspberry Pi is a small, easily removable breakout that easily adds a 4-pin JST SH pin (Stemma QT or Qwiic) connector to your Raspberry Pi. The SHIM design allows you to plug directly to the Pi’s I2C bus with no soldering required, and the thin PCB design allows for it to be sandwiched on your Pi GPIO with other bonnets or HATs! The Qwiic SHIM works great if you want to add a Qwiic connector to your Pi simply and easily with no soldering required.
Binho Qwiic / Stemma QT Interface Board: This board makes it easy for you to interface your Binho Nova host adapter with up to 4 strings of Qwiic / Stemma QT I2C devices. It also breaks out all of the pins to a series of headers for convenient jumping to other circuits or perhaps your logic analyzer to monitor everything while you develop and debug.
Binho Breadboard Breakout: This board breaks a male 2×5 1.27mm connector out to breadboard-friendly 2.54mm / 0.1″ pitch headers. It’s an easy way to interface your Binho Nova host adapter with other circuits using standard jumper wires as well.
Binho Feather / Stemma QT Interface Board: This board makes it easy for you to interface your Binho Nova host adapter with any Feather form-factor device. I2C, SPI, and UART interfaces are all wired up. By default, the 3V3 and 5V rails are connected so that the Binho Nova can power the sensors, but this can be easily disabled by cutting the exposed traces. Additionally, this interface board features a STEMMA QT / Qwiic connector to easily bridge the Feather and Qwiic ecosystems.
Binho Nova Multi-Protocol USB Host Adapter: The Binho Nova Multi-Protocol USB Host Adapter allows you to interface your computer directly to hardware circuits. This device is powered by the USB connection to the host PC and is also able to provide downstream power to test circuits. This learn guide details how to use a Binho Nova with CircuitPython libraries to interface with sensors and components via I2C (Inter-Integrated Circuit), SPI (Serial Peripheral Interface), GPIO’s (General Purpose Input/Output), or UART (Universal Asynchronous Receiver/Transmitter).
