The module ASIC driver HT1632C lattice, without requiring an MCU scan, do not take MCU resources, 16 adjustable brightness, saving three IO lines / four-wire interface module is reserved for a ATMEGA8 microcontroller, AVR USB, mini USB Chip Block, buzzer, 18B20 temperature sensor, LED metering port, infrared receiver interfaces, RTC clock module (reserved), three separate buttons, AD input supply voltage can be measured, easy to do secondary development. The module is pre-installed basic HT1632C peripheral circuits and ATMEGA8 +32768 crystal, other parts required to install itself. the purchase of the module schematics, AVR sample program.
As the color reasons, looks like a yellow dot is actually red.
Time, date adjustment, with leap year compensation (2000 - 2099)
Date and temperature every 5 minutes to scroll through once (the version without 18B20, temperature invalid, buy their own installation)
The time display on the move
16-level brightness adjustment
Power: 3V ~ 5V
Minimum operating current:
Maximum Operating Current:
Dimensions: 6.85 in x 1.50 in x 0.59 in (17.4 cm x 3.8 cm x 1.5 cm)
Weight: 2.86 oz (81 g)
Compared to the previous version this version has improved these functions:
The power added MOS tube to prevent reverse
Increase the polarity identification
Driver chip add two tantalum capacitor filter and no working noise
Download interface has changed IDC10 to IDC6, need to welding
Reserved RTC has modified from DS1302 to DS3231 high precision clock chip
Modify the position of some components
The electronic clock did not go when the power-down function, described on the instructions provided to achieve the source, only for learning to use open source, do not promise custom functions will continue to provide follow-up version of the source.

3.5mm Audio Socket Stereo Sound Module w/ Mic for MP3 Player – Red
The audio-style connectors that you see on some phones, MP3 players and development boards. TRRS stands for "Tip, Ring, Ring, Sleeve," which reflects the fact that, unlike a standard stereo connector, this actually has three conductors and a ground. Some devices use the extra conductor for a microphone.
