Request for Recommendation of a Smaller Connector Part for ESP programming

[sandeep]

Hi Espressif Team,

We are currently using the 1775443-5 connector (5 pin, 1.5mm pitch) for programming and debugging the ESP8266 in our hardware. To optimize PCB space, we are seeking a smaller alternative with similar specifications.

Could you recommend a more compact connector that meets these requirements? We are only using 3 pins (Rx, Tx, and GND) from the current 5-pin configuration. Any datasheets, part numbers, or links to relevant products would be greatly appreciated.
