NodeMCU CP2102

NodeMCU developed based on the ESP-12E, compatible with existing versions.
Uses a brand-new (not second-hand) original CP2102 chip.
New design with a more durable USB interface.

Description

A motor driver expansion board based on the ESP-12E.
Motor power supply range: 4.5V to 36V
Control power supply range: 4.5V to 9V
The motor power supply and control power supply are separated. During experiments, they can be combined using a jumper cap to short VIN and VM, allowing both the motor and control board to be powered simultaneously.

Product Specifications

Power Input:
Motor power supply (VM): 4.5V to 36V, can be powered independently
Control power supply (VIN): 4.5V to 9V (10V MAX), can be powered independently
The module provides a jumper to short VM and VIN, allowing a single power supply (must be 4.5V to 9V) to drive both the motor and the control system at the same time
Logic operating current (Iss):
≤60mA (Vi = L)
≤22mA (Vi = H)
Drive section operating current (Io): ≤1.2A
Power dissipation: 4W (T = 90°C)
Control signal input level:
High level: 2.3V ≤ VIH ≤ VIN
Low level: -0.3V ≤ VIL ≤ 1.5V
Operating temperature: -25°C to +125°C
Drive mode: Dual-channel high-power H-bridge drive
ESP-12E Dev Kit control pins:
D1, D3 (Motor A)
D2, D4 (Motor B)
Module weight: Approx. 20g

Notes:

When inserting the ESP-12E module, please ensure that the antenna direction is aligned with the direction of the expansion board. By using the jumper cap, the control board and the motor can be powered at the same time.
