This board is ~half of the NodeMCU v3 board, including a micro USB connector, a CP2102 serial converter, and the transistors needed to toggle the RST and IO0 lines to enable button-less flashing. IO0 and RST also have momentary switches. Power is supplied via an AP2112 LDO, which can deliver 300mA at 3.3V, which is enough for the ESP8266/ESP32 itself, but not many peripherals.

RX/TX and Power LEDs are included but make sure to use CP2102N for these to work. CP2102 doesn’t have the GPIO pins, but is otherwise pin-compatible..

This model is verified to work at 1.5Mbaud flash rates on ESP8266 and ESP32.

This is a four port MOSFET driver board, with an onboard 3.3V LDO regulator. Best used with 2oz or more copper pours, is rated for 10Amps. MOSFETs used need to be driven with a Vgs saturation of 3.3V or better, typically FQP30N06L or RFP30N06LE are used.

The onboard power supply (AMS1117) yields 1A max for the driving device, so if a VIN voltage higher than 15V is supplied, an external DC/DC converter that brings the high voltage (up to 60V max) is needed to bring the voltage down to 12V or less (typically 5V).

This is a four port Songle 5V relay board, with an onboard 5V transformer and 3.3V LDO regulator, using ULN2003A for flybacks and to switch up 3.3V input signals to the relays. Best used with 2oz or more copper pours, is rated for 10Amps.

The power supply is 1A max, the relays pull ~300mA when they’re all on, leaving 700mA for the driving device.

This is an ESP8266 (Variant 12E) with a PCA9685 PWM controller on I2C (Variant TSSOP28) and 4 JST-SH (1.0mm) connectors. It also has a QWIIC connector to connect other I2C devices, and a 6-pin JST-SH connector for serial and flashing, and 2 LEDs.
