Supports dual-level logic from 3.0V to 5.5V , making it compatible with both 3.3V (modern microcontrollers) and 5V (standard Arduino Uno) systems.
The HW-044 is a self-contained, dual-axis analog joystick module. It is often incorrectly referred to as a "PS2 joystick module" because its physical form factor and electrical behavior mimic the thumbsticks found on PlayStation 2 controllers. The module outputs two independent analog voltages (X and Y axes) proportional to the stick’s position, along with a digital output for a built-in push-button switch that activates when the stick is pressed down vertically (the "SEL" or "KEY" signal). hw-044 datasheet
: These help in understanding how the component performs under different conditions. For example, a graph showing how the voltage output of a regulator changes with input voltage or load current. Supports dual-level logic from 3
The is a popular, low-cost RS232 to TTL converter module based on the MAX3232 transceiver IC . It is primarily used to bridge the communication gap between devices that use RS232 serial standards (like older PCs, industrial equipment, or GPS modules) and microcontrollers that use TTL logic levels (like Arduino , ESP32 , and Raspberry Pi ). Core Technical Specifications The module outputs two independent analog voltages (X
