TTL-RS232 serial communication module
1. Module introduction:
The TTL-RS232 module is based on the SP3232EEN-L / TR chip, which is used to realize the mutual conversion between TTL / COMS level and RS232 level. Wide operating voltage, compatible with 3.3V and 5V systems. TTL / CMOS data input / output terminals have LEDs to indicate the data receiving and sending status.
2. Module features:
Working voltage: 3.0V ~ 5.5V
Chip power consumption: 0.3mA (no load, AMB = + 25 °, VCC = 3.3V)
Maximum baud rate: 235Kbps (RL = 3kΩ, CL = 1000pF)
Interface: DB9_Female, easy to use
