The Seeed Studio XIAO RP2040 is as small as the Seeed Studio XIAO SAMD21 but it's more powerful. On one hand, it carries the powerful Dual-core RP2040 processor that can flexible clock running up to 133 MHz which is a low-power microcontrollers. On the Seeed Studio XIAO RP2040 there is also 264KB of SRAM, and 2MB of on-board Flash memory which can provide more program to save and run. On the other hand, this little board has good performance in processing but needs less power. All in all, it is designed in a tiny size as small as a thumb(20x17.5mm) and can be used for wearable devices and small projects.

The Texas Instruments CD4049UB and CD4050B are a family of CMOS Hex Inverting Buffers and Converters that feature logic-level conversion using only one supply voltage (Vcc). The CD4049UB variant offers inverting buffers, whereas the CD4050B provides noninverting buffers. Both devices are capable of driving two TTL loads directly, thanks to their high sink current capabilities. They are designed for high-to-low level logic conversion, CMOS to DTL or TTL Hex Converters, and can also serve as CMOS current sink or source drivers. These components are tested for quiescent current at 20 V and ensure a maximum input current of 1 µA at 18 V over the full package temperature range, with a significant reduction to 100 nA at 18 V and 25°C, making them suitable for power-sensitive applications. With 5-V, 10-V, and 15-V parametric ratings, they offer flexible options for various design requirements. The CD4049UB and CD4050B are provided in a variety of package options including PDIP, SOIC, and TSSOP, catering to a wide range of assembly and application scenarios.

The TPS61187, manufactured by Texas Instruments, is a high-efficiency, white-light-emitting-diode (WLED) driver specifically designed for notebook LCD backlight applications. This component can manage an input voltage range of 4.5 V to 24 V and supports a maximum output voltage of 38 V. It is distinguished by its integrated 2-A, 40-V power MOSFET and the capacity to drive up to 60 WLEDs arranged in six channels, with each channel capable of supporting a maximum current of 30 mA. The TPS61187 ensures high precision in current regulation and matching across all channels. Notably, the device offers versatile dimming capabilities through both automatic phase-shift and direct-PWM dimming methods, accommodating a wide PWM dimming frequency range from 100 Hz to 50 kHz in Direct PWM mode and 100 Hz to 22 kHz in Frequency Programmable mode. The boost output automatically adjusts to the WLED forward voltages to enhance efficiency. Additionally, the TPS61187 features programmable switching frequency between 300 kHz and 1 MHz, overvoltage protection, thermal shutdown, and built-in protection against open or short circuits on the WLED string. Available in a 20-pin WQFN package with a nominal body size of 4.00 mm x 4.00 mm, the TPS61187 offers a compact solution for driving notebook backlighting, providing engineers with a flexible and efficient option for their designs.
