JY-MCU 3208 Lattice Dot Matrix Clock HT1632C Driver With MCU
close

Description:

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.

Feature:

Time display
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

Specification:

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

Note:

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.

Package included:

1 x Dot matrix clock

3.5MM Audio Socket module

3.5mm Audio Socket Stereo Sound Module w/ Mic for MP3 Player – Red
Description:
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. 

MaxPower 2312 960KV Motor (For DJI Phantoms) CW/CCW Set (4pcs)
close

Features:
100% Brand new and high quality
The double layer, single wire stator technology increases slot wire embedding degree and improves heat dissipation. Also, the single wire stator design improves motor efficiency and its ability to withstand a larger current, ensuring consistency in the motor's performance. 
The new bearings, with a higher durability and ability to withstand greater impacts, are used to avoid damage in the event of an accident, greatly reducing maintenance costs. 
New insulation coating powder is used to improve the stator voltage capacity, ensuring the working life and stability of the motor.
The electromagnetic design and lightweight structure, customized for the Phantom, has increased maximum output power by nearly 25% without adding extra weight.
The new propeller adopts a 4.5 inch pitch, which when used with the 2312 motor can provide an extra 200g/axis of output thrust, giving you both power and flexibility. Furthermore, your Phantom’s flight time is not reduced, because of the increased aerodynamic performance and motor efficiency.

74HC04 Hex Inverter
close

The MM74HC04 inverters utilize advanced silicon-gate CMOS technology to achieve operating speeds similar to LS-TTL gates with the low power consumption of standard CMOS integrated circuits. The MM74HC04 is a triple buffered inverter. It has high noise immunity and the ability to drive 10 LS-TTL loads. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.

Features

■ Typical propagation delay: 8 ns

■ Fan out of 10 LS-TTL loads ■ Quiescent power consumption: 10 µW maximum at room temperature

■ Low input current: 1 µA maximum
