This is a "submodule" board for the Kube v2 multi sensor project (https://www.pcbway.com/project/shareproject/NodeMCU_v_1_2_Board.html). It is a cerrier board to add additional I/O to the Kube "stack", using the MCP23017 chip for 16 channels of digital I/O, and/or the ADS1115 breakout board (thin or wide) from Adafruit for 4 channels of 16-bit analog input.

The MCP23017 chip address pins are broken out, so you can optionally stack up to 8 of these boards for 128 total digital I/O.

The ADS1115 chip address pin is also broken out, and you can address/stack up to 4 of these units, for 16 total analog I/O channels.

All I/O is broken out to terminal blocks, for easy connections.
