The AAR121-10 is an LED Character and Numeric display module produced by Avionic Instruments. It is a compact, single-channel, high-brightness display module equipped with an advanced power management system that is suitable for applications in both aviation and other industrial fields.

The AAR121-10 module comprises one 7-segment digits and 4-character areas. The segment combinations of each character area can be customized according to customer requirements, suitable for a range of different applications.

The AAR121-10 can be used in highly demanding applications due to its advanced input and output design and power management system. The input design consists of a temperature-compensated, precision analog-to-digital converter (ADC) with a resolution of 10-bits and a logic interface compatible with STM32 and HC12 microcontrollers. The output design comprises a 5-bit-wide PWM signal for each character area. The PWM signal controls the brightness of the characters, allowing them to be dimmed or adjusted according to the needs of the user.

Unlike other display modules, the AAR121-10 also features onboard power-saving features and an adjustable power supply. The built-in power-saving features allow the module to consume only the energy needed to drive the display, while still maintaining a high degree of brightness. The adjustable power supply allows the module to be powered from a range of sources, such as 1.7V up to 5V direct current (DC). This makes the module suitable for a variety of applications.

The AAR121-10 is a very capable LED Character and Numeric display module. Its advanced input and output design coupled with its onboard power-saving features and adjustable power supply make it suitable for a range of highly demanding applications. It is an ideal choice for applications in both aviation and other industrial fields.
