📣 Firmware Update Release:
Firmware Version v0.23 is now released! Please follow the link here or update via Cloudloop Device Manager.
RockREMOTE Mini (OEM)
RockREMOTE Mini OEM is a compact, low-power subassembly designed for integration into bespoke solutions.
The built-in Iridium Certus 100 (9770) supports IP (TCP, UDP and ICMP) connections and the more efficient Iridium Messaging Transport (IMT) protocol.
Ground Control provides integration guidance and support through the Iridium review process. Compliance of the completed system remains the responsibility of the OEM equipment manufacturer; see the Mini OEM Integration Guide for details.
Designed for easy installation using just 4 screw mounts.
| Item | Specification |
|---|---|
| Supply voltage | 10 – 30V DC |
| Power consumption (Sleep) | < 36mW/75mW (12V/24V) |
| Power consumption (Idle – Rx mode) | 300mW (Typical) |
| Power consumption (Average Transmit) | 7.25W |
| PEAK current draw | <1.66A@12V, <833mA@24V, 10% duty cycle during Iridium transmit. |
| Inrush Current | ~ 800mA |
| Serial interface | RS232, RS422 and RS485 |
| UART | Logic level UART (Debug - Dev use only) |
| GPIO | 4 configurable channels (compatible interface hardware required) |
| Operating temperature/humidity | -40℃ to 70℃, ≤ 95% RH |
| LAN | 10/100 wired Ethernet |
| WAN | Iridium Certus 100 |
| Bluetooth | BLE 5.0 using the RockCONNECT IoT app |
| Iridium antenna connection | MMCX (TNC when using the OEM developer board) |
| GNSS antenna connection | U.FL (SMA when using the OEM developer board) |
| Dimensions | 155.8 x 77.2 x 42.5mm (L x W x H) |
| Weight | 288g |
When powering the unit without an Iridium antenna connected it is important to terminate the RF connection with an RF load to reduce the risk of failure in the 9770 modem RF amplifier stage. A suitable load is 202117 from Amphenol.

Pinout
The part number of the header fitted to the PCBA is Molex 877603016
NOTE: This pinout is DIFFERENT from the Pro-OEM

OEM developer board
In order for customers to trial the Mini OEM functionality and to provide a reference design we are able to provide the OEM connector PCBA pictured below. This gives access to all functions brought out on the 30 pin header and includes magnetics and RJ45 connection for Ethernet. The latest revision of this board also includes positions for mounting TNC and SMA connectors.
Note the required orientation of the interface board with the terminals along the upper edge. Inverting the board on the 30 way header WILL DAMAGE the OEM board. See image below.

The OEM connector PCB is designed to slide into the mounting “feet” slots on the RockREMOTE Mini OEM as pictured above.
However, it cannot be installed with the feet in place.
- Unscrew and remove the mounting feet (on the connector side) from the RockREMOTE Mini OEM.
- Position the OEM connector PCB onto the header pins, ensuring all pins are correctly aligned, then slot it in carefully.
- Reinstall the mounting feet, ensuring the sliders fit into place and lock the PCB securely in position.
Do not attempt to force the PCB into the slots with the feet installed.
Doing so will damage the connector header pins!
