**Question**

We’re reviewing the documentation for GigaBlox and have come across both Revision C and a Revision D datasheet referencing **BB-GGB-D-1-NDAA**.

Is **BB-GGB-C-3-NDAA** the correct part number for the NDAA version? Does the standard Revision C datasheet apply to it, or is there a separate datasheet? Is Revision D an upcoming replacement?

**Answer**

As of September 2026, the current GigaBlox revision is **Revision C** , and **BB-GGB-C-3-NDAA** is the correct part number for the NDAA version.

The [GigaBlox Revision C datasheet](https://store-l0hv1zrcre.mybigcommerce.com/content/GigaBlox%20DataSheet%20C_I.pdf) applies to both **BB-GGB-C-3** and **BB-GGB-C-3-NDAA**. There are no functional or dimensional differences between these two parts.

**Which part number should I use?**

Use the following part numbers when specifying the Revision C hardware:

| Version | Part number | Applicable datasheet |
| --- | --- | --- |
| Standard GigaBlox | BB-GGB-C-3 | Revision C |
| NDAA GigaBlox | BB-GGB-C-3-NDAA | Revision C |

The NDAA version does not require a separate datasheet for its functionality or dimensions.

**What happened to Revision D?**

Revision D was originally planned, but BotBlox ultimately decided not to proceed with it. The **BB-GGB-D-1-NDAA** reference comes from that planned revision and should not be treated as an upcoming replacement for Revision C.

If you have received a Revision D datasheet, use the Revision C datasheet linked above for the parts listed here.

**Does the Revision C datasheet also cover earlier part numbers?**

Yes. BotBlox has confirmed that the Revision C datasheet applies to the following part numbers:

- **BB-GGB-C-1**

- **BB-GGB-C-CO1**

- **BB-GGB-C-CO2**

- **BB-GGB-C-3**

- **BB-GGB-C-3-NDAA**

For a specification or purchase request requiring the current NDAA version, use **BB-GGB-C-3-NDAA** together with the **Revision C datasheet**.
