24-Pack AMS1117 LDO Regulator Module, 3.3V + Adjustable

• 24-PIECE KIT (18x FIXED + 6x ADJUSTABLE) Includes 18 AMS1117-3.3V fixed modules (with LED indicator) and 6 AMS1117-ADJ adjustable modules — for voltage regulation, converting higher inputs to stable 3.3V or custom outputs.
• LOW DROPOUT DESIGN LDO regulators dissipate excess voltage as heat — suitable for light-duty use where input is higher than output (e.g., 4.3V–12V for 3.3V output). Not recommended for high-current/heavy loads, as more voltage drop or current produces more heat.
• ADJUSTABLE OUTPUT & STABILITY ADJ modules feature a rear potentiometer for tunable output (1.25V and up). Once set with the included screwdriver, output stays consistent even if input varies (as long as input exceeds output by ~1V).
• BREADBOARD-FRIENDLY Compact modules (20mm x 11mm x 5mm) with 3 pins (GND, OUT, VIN). 3.3V versions include an LED for power status — for Arduino, Raspberry Pi, sensors, and prototyping without soldering.
• WIDE COMPATIBILITY Works with microcontrollers such as Arduino, Raspberry Pi, ESP32, ESP8266, STM32, and various 3.3V/5V sensors and modules. Includes a storage container, mini screwdriver, and male header pins.

Lonely Binary 24pcs AMS1117 LDO Regulator Kit (18x Fixed 3.3V + 6x Adjustable)

The Lonely Binary AMS1117 LDO Regulator Kit is a 24-pack for voltage conversion in breadboards, microcontrollers, and DIY electronics. The set includes 18 fixed 3.3V modules and 6 adjustable modules for handling voltage mismatches.

Key Features

AMS1117-3.3V Modules: Deliver a stable 3.3V output from higher inputs, with three pins (GND, OUT, VIN) and a built-in LED to indicate operation. For powering 3.3V devices like ESP32 or sensors from 5V sources.

AMS1117-ADJ Modules: Adjustable output via a rear potentiometer, from about 1.25V upward. The output remains fixed once set, regardless of input fluctuations (as long as input exceeds output by ~1V).

LDO Technology: As Low Dropout Regulators, these convert excess voltage to heat for stable operation. Higher voltage drops or currents generate more heat — avoid continuous heavy usage (e.g., over 800mA) without heatsinks to prevent thermal issues. Input must always be higher than output.

Breadboard-Ready: Compact PCBs with included male pins for quick setup. For Arduino, Raspberry Pi, ESP32-S3, and custom circuits.
