HOTRC DS-600 6CH 2.4GHz FHSS Radio System Transmitter Remote Controller GFSK 6CH Receiver PWM TTGO T-Call V1.4 ESP32 SIM800L Wireless Communication Module We recommend using a simple

We recommend using a simple resistor divider on RX (10k and 20k resistors) or a dedicated logic level converter IC for reliable operation and maximum module lifespan

The flow rate depends on tube inner diameter and motor speed control

and implement AT command parsing in your firmware

Self-Locking Note: 4-start lead screws with 8mm lead are generally NOT self-locking

minimizing idle time between power-on and productive work
