Hexabitz modules have a number of internal SMD pads that are accessible only from top or bottom—not from module side. These are used for non-essential signals like MCU reset and SWD port. Instead of soldering SMD connectors there, you could use a nice off-the-shelf E-Z-Hook kit that we assembled for you.
The kit consists of:
- 0603 SMD probe pads (down left) – quantity 10.
- E-Z-Micro-Hook double grip connectors (upper left) – quantity 4.
- Female-to-female patch cable with 0.025” square ends (right) – quantity 4.
These cables and hooks are typically color-coded.
