CJMCU-1286 PIC16F1823 Microcontroller Development Board

Features :

1. Mini design, portable and easy to use.
2. It is the audio-style connectors that you see on some phones, MP3 players, and development boards.
3. 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.
4. Some devices use the extra conductor for a microphone (like hands-free headsets) or to carry a video signal (like in some MP3/MP4 players).

Specifications:

1. On-board LM358 chip
2. Adjustable gain up to 100x
3. On-board 10K adjustable resistor for gain adjustment
4. On-board power indicator
5. Chip has been drawn out to the main pins for direct input and output of signals
6. Working Voltage Range: 5 V to 12 V
7. Board Size: 32.7 x 13.3 mm

Features:

1. 2V to 6V operation
2. “On” resistance: 70 Ohms @ 4.5V
3. 6ns break-before-make @ 4.5V
4. Wide operating temperature range: -55C to 125C
