GPS receiver module (GY-NEO6MV2) and ESP32 microcontroller & cable set. - GPS receiver module (GY-NEO6MV2) (2 pieces) - Microcontroller: ESP32 - Accessories: Micro USB 2.0 cable - Antenna: External antenna (included) - GPS receiver module tested for reception - ESP32 is marked with the Technical Regulations Compliance Mark (Japan) - ESP32 has been checked for writing Feel free to negotiate the price; Please use the "Price Negotiation" button in the lower right of the image. Thank you for viewing. Due to long-term use, all three products have oxidation on the surface of the metal parts. (Masking tape is wrapped around one antenna to prevent oxidation. The other antenna has oxidation on the back.) All have been tested and are working. If the microcontroller is not recognized, please reconnect the cable. It should definitely be recognized as I have confirmed its operation. When using the microcontroller and GPS module, be absolutely careful not to mix up the positive and negative wires. There is a risk of failure if the wiring is incorrect. If it doesn't work when assembled on a breadboard, the quality of the breadboard may be poor or there may be poor contact. If you are using one, I recommend a high-quality breadboard from Sunhayato.
