As can be seen from the designation V3, the board is only for "NodeMCU Lua Lolin V3 Module ESP8266 ESP-12F WIFI". The board is too wide for "NodeMCU Lua Amica Module V2 ESP8266 ESP-12F WIFI" although both microcontrollers have 15 pins. I haven't found anything suitable for the Amica either. Perhaps the board "ESP8266 WiFi Motor Drive Expansion Board For NodeMCU ESP-12E" is suitable for the Amica, since there are also additional plug-in options on this board. At least you can put the narrower Amica on it and use additional pins on the board. For ESP 32 microcontrollers I ordered the "Keyes ESP32 Core Board Development Expansion Board Equipped with WROOM-32 Module" as a test, because the ESP 32 has 19 pins. The variety of microcontrollers is very confusing, which is why I mainly use the Arduino Uno or Nano. The Arduino Nano also has 15 pins, but is even narrower than the Amica, which is why Nano boards cannot be used for the Amica. See More
