WisBlock Mini Base + Power Kit – RAKwireless RAK19009 + RAK19012

This bundle is built for compact WisBlock systems where you still want proper USB-C bring-up and flexible field power. WisBlock uses a modular building-block approach: a WisBlock Core plugs into a Base board and is expanded with additional modules. The WisBlock Base platform uses high-speed interconnect connectors to help ensure reliable signal integrity when assembling custom devices.

The RAK19009 WisBlock Mini Base Board with Power Slot is designed for small builds and provides:

1× WisBlock Core slot

2× sensor slots
making it a good fit for compact sensor nodes that only need one or two sensor expansions.

As stated in the text, the baseboard separates power from the board to support a wide variety of supply options—so it must be paired with a suitable power board. That’s why the kit includes the RAK19012 WisBlock USB LiPo Solar Power Slot Module.

The RAK19012 is a power board that provides USB-C for programming, debugging, and firmware uploading to the WisBlock Core. It also includes a battery connector with an onboard charger, a solar panel connector, charge-status indication, two user-configurable LEDs, and a reset button. This enables battery-powered prototypes and field deployments with optional solar charging (within the stated limits). The text also recommends the WisBlock IO Pin Mapping Tool to prevent pin conflicts when combining modules.

Notes stated in the text: fasten modules with screws for proper function. Only 3.7–4.2 V rechargeable Li-ion batteries are supported. Only 5 V solar panels (up to 6 V) are supported; do not use 12 V panels.
