Feature:
1. Practical Use: Intelligent recognition chip type supports mixed use of learning codes and fixed codes (welding codes) IC remote control such as EV1527, PT2262, etc.
2. Broad Utility: Compatible with most learning codes and fixed codes (welding codes) chips on the market, including EV1527, PT2262, HX2262, SC2260, SC5211, HS2240, etc.
3. Reliable Work: Intelligently adapt to the oscillating resistance of the transmitter, no need to consider the oscillating resistance of the transmitter.
4. Stable Operation: Good local oscillator radiation suppression ability, multiple modules can work together without mutual interference, and does not affect the receiving distance.
5. Working Modes: TYJM01AK supports 3 working modes, self locking (T4), jog (M4), and interlocking (H4).
6. 4 Channels Output: Support 4 channels of output, the module comes with learning indicator and VT data effective indication, the operation is more intuitive and convenient. Decoding chip built in EEPROM, supports up to 32 groups of remote control memory.

Specification:
Item Type: Remote Control Module
Working Voltage: 2-5.5V;
Working Current: 3.5mA (433MHz fully working);
Working Frequency: 433MHz; 
Modulation Method: ASK/0OK;
Receiving Sensitivity: -108dBm;
Data Rate: Up to 10kpbs;
Each I0 Port Drive Capacity of : Pin Function Description:
VT: Learning button input terminal and decoding valid output terminal, output low level when decoding is valid, otherwise it is high input state;
D3: Data output terminal D3 channel;
D2: Data output terminal D2 channel;
D1: Data output terminal D11 channel;
D0: Data output terminal D0 channel;
VCC: Positive power supply;
GND: Negative pole of power supply;
Working Mode Description:
1. Self Locking (T4): Four independent outputs without mutual influence. Each time you press the launch button, the output state of the corresponding output terminal is reversed once, with VT pulse output; for example, the data of the A button is 0010, then every time you press A key once, the state of D1 channel will be flipped once;
2. Jog (M4): Press the launch button, the corresponding output terminal will output high level, and return to low level after stopping transmission, with VVIT pulse output;
3. Interlock (H4): Press the launch button, the corresponding one channel outputs high level, all other channels are low level, and keep it until another time the remote control data changes, the valid signal is identified by judging the T pulse; for example, the data codes of the button is 1000, then the D3 channel is high lev
