SparkFun Logic Level Converter - Bi-Directional Step Down 5V Signals to 3.3V and Steps up 3.3V to 5V Board Dimensions: 0.63 x 0.52 (16.05 x 13.33mm)

The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time.
The SparkFun bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices.
The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the 'HV' pin, low voltage (3.3V for example) to 'LV', and ground from the system to the 'GND' pin.
What really separates this Logic level converter from our previous versions is that you can successfully set your high and low voltages and step up and down between them safely on the same channel.
Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side. Board Dimensions: 0.63 x 0.52" (16.05 x 13.33mm)

SparkFun Qwiic Pocket Development Board - ESP32-C6 Mini-1 Module, Including a USB-C Connector, Qwiic Connector, 2-pin JST Battery Connector, Board Dimensions: (Inches) 1" x 1"

The SparkFun ESP32-C6 Pocket Dev Board is built around a RISC-V single-core processor with 4 MB flash memory in a 1"x1" Qwiic Standard Footprint!
It features the ESP32-C6 Mini-1 module. We designed this board with components on both sides of the PCB to squeeze as many features as possible into its tiny footprint, including a USB-C connector, Qwiic connector, 2-pin JST battery connector with an on-board charging circuit, as well as two buttons for Reset and Boot. The design also works to optimize power consumption.
Features: Up to 7 12-bit ADC Channels, Up to 2 UART Channels (with flow control) USB Serial, One Low Power UART Channel, One I2C Channel, One Low Power I2C Channel, LED PWM, One I2S Channel, 4 MB Flash.

Though some are tied to specific pins, many of these peripherals can be mapped to any GPIO pin. Due to the board's size, it only breaks out eight total GPIO pins, including four ADC-compatible pins, Low Power and Standard UART, and an extra two GPIO pins. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.
