2.3.2 4G Module
The reComputer R1000 mainboard features two Mini-PCIe slots, with Mini-PCIe slot 1 supporting a 4G module using the
USB protocol. The EC25 4G module from Quectel has been fully tested to be compatible with the reComputer R1000.
Please note that if you require 4G functionality, it is necessary to purchase the corresponding 4G module and external
antenna, and follow the instructions in section 4.4 "Assemble 4G/LoRa®/Zigbee Module and Antenna".
2.3.3 LoRa® Module
Both two Mini-PCIe slots supports LoRa® module using the USB protocol. Meanwhile, Mini-PCIe slot2 supports a LoRa®
module using the SPI protocol. The WM1302 module from Seeed Studio has been fully tested to be compatible with the
reComputer R1000.
Please note that if you require LoRa® functionality, it is necessary to purchase the corresponding LoRa® module and
external antenna, and follow the instructions in section 4.4 "Assemble 4G/LoRa®/Zigbee Module and Antenna".
2.3.4 Zigbee Module
The Mini-PCIe slots offer support for Zigbee modules utilizing the USB protocol, allowing for seamless integration of Zigbee
functionality into compatible devices. This feature enables efficient communication and control within Zigbee networks,
enhancing the versatility and connectivity of the system. With two Mini-PCIe slots available for Zigbee modules, users have
the flexibility to implement diverse applications for enhanced reliability.
Please note that if you require Zigbee functionality, it is necessary to purchase the corresponding Zigbee module and
external antenna, and follow the instructions in section 4.4 "Assemble 4G/LoRa®/Zigbee Module and Antenna".
2.3.5 PoE
The reComputer R1000 can support the IEEE 802.3af PD (Powered Devices) standard by adding a PoE power supply module.
The seat for PoE is pre-soldered on board; however, users need to disassemble the device to install the PoE module for
Ethernet PoE function. For guidance on disassembly, please refer to section "4.1 Disassembly Guide." For more detailed
information about PoE power supply, please refer to section "2.3.6 PoE."
The reComputer R1000 supports PoE power supply, but the standard product does not include a PoE module by default.
Seeed can provide PoE soldering and assembly services for batch customization orders. However, if a customer is
testing a sample, they will need to solder and assemble the PoE module themselves. Instructions on how to do so,
please refer to section 4.5 "Assemble PoE Module" for detailed.
2.3.6 SSD
The reComputer R1000 supports 2280 NVMe SSD through the use of a PCIe slot(J62) below two Mini-PCIe slots on board. It
is important to note that the CM4's PCIe is gen2.0 with a maximum theoretical speed of 5Gbps. If you are using a Gen3.0 or
higher SSD, it may not be able to achieve the SSD's maximum speed. After testing, the reTerminal DM with installed SSD
can achieve a maximum write speed of 230MB/s and a maximum read speed of 370MB/s. If you are unsure which SSDs are
compatible, you can purchase following the accessories list below.
Please note that:
1- The speed test results may vary depending on the SSD model, testing method, and testing environment. The values
provided here are for reference purposes only and were obtained in Seeed's laboratory.
