Mini MAX3232 level to TTL level conversion board

Product features:
Chip: domestic max323cse
Voltage range: 5V
Height limiting baud rate: it is recommended not to be higher than 120kbps
Size: 16mm*9.5mm (pure manual measurement, please understand if there is any error)
The figure below shows the front and back sides of the module. The power supplies on both sides are connected together. Only one side needs to be connected. Two independent channels on both sides can be used. The arrow indicates the signal flow direction. It indicates that it is input to the inside and output to the outside. The end near the RS232 character is the RS232 level, and the end near the TTL character is the TTL level.

Product features:
Module chip: txs0108e
Size: 26mm*15.5mm (pure manual measurement, please understand if there is any error)
High speed full duplex 8-channel level conversion module
Provide two-way communication capability

OE can make the IO high level effective. It is recommended to connect the IO port at the low voltage terminal

Product features

Warm tips: This product is a level conversion module, not a power conversion module! 5V power supply must be connected for normal operation!

1. 4mos transistor realizes bidirectional conversion of four 3V and 5V levels,
2. The power input is provided with anti reverse connection protection, integrated with 3.3vldo, and can provide external current not greater than 150mA,
3. With power indicator light, whether it works or not is clear at a glance,
4. It can realize bidirectional conversion of 3v~5v level of UART, IIC, 1-wire, SPI and other bus signals.

2-channel level conversion module 3.3V to 5V

8-channel level conversion module 3.3V to 5V

Since this product is 3.3V, it is inconvenient to connect to a conventional 5V sensor. Therefore, this product realizes the bidirectional conversion of 8-channel high-voltage logic and low-voltage logic, and realizes the bidirectional mutual conversion of ax and BX.
Conversion level range: 1.8v~6v

instructions

(take 3.3V and 5V mutual conversion as an example)
Vcca connected to 8-channel level conversion module 3.3V power supply
Vccb is connected to 5V power supply (it can be external 5V power supply)
GND is connected to negative pole of power supply, and two power supply sites
Ax input 8-channel level conversion module 3.3V TTL level, BX will output 5V sensor module TTL level
BX input 5V electronic module TTL level, ax will output 8-channel level conversion module 3.3V TL level.
