Description 3.96Port Unit is an HY2.0-4P to HT3.96 interface converter for M5Stack Grove wiring. The 3.96Port Unit converts an HY2.0-4P cable into a freely pluggable 4-pin terminal interface, making power and ground connections easier to handle in small control projects. The HT3.96 connector used by the 3.96Port Unit is a common pluggable terminal connector specification. With a 4-pin female terminal block, through-hole mounting, and two LEGO-compatible holes, the 3.96Port Unit is useful for socket control, power switch wiring, and compact prototyping that needs removable terminal access. Features 3.96Port Unit converts HY2.0-4P Grove wiring to an HT3.96 pluggable terminal interface. Includes one 4-pin HT3.96 female connector. Supports convenient power and ground interface connection. Through-hole terminal format with 0.156" (3.96mm) pitch. Two LEGO-compatible holes for mechanical mounting. Compact Unit form factor for M5Stack extension and prototyping work.

Product List 1 x Unit 3.96 1 x HY2.0-4P Grove connection cable (20cm) 1 x HT3.96 female connector Other Content Connector Use The 3.96Port Unit adapts the Grove-side HY2.0-4P connection to an HT3.96 terminal block, so field wiring can be inserted and removed more easily than with a fixed cable connection. Mechanical Mounting The board includes two LEGO-compatible holes, making it easier to secure the 3.96Port Unit in small builds or M5Stack prototype assemblies.
