LEC-RB5SMARC 2.1 short size Computer-on-Module with Qualcomm QRB5165 SoC and 15 TOPS NPU
- Manufacturer
LEC-RB5 is an 82 x 50 mm SMARC short size CPU module compliant with SMARC revision 2.1.1: the processing sits on the module, while the I/O is routed out on your carrier. The Qualcomm QRB5165 SoC with Arm Cortex-A77 cores makes it suitable for robotics, AMRs and vision devices, where footprint and power consumption matter.
On the management side there is the SEMA board controller and a 30-pin debug header for JTAG and BMC access; security relies on the Qualcomm Secure Processing Unit and the TPM 2.0 module. The reference operating system is Linux, with Canonical Ubuntu and Yocto.
Configurations: the -CT (0~60 °C) and -ER (-20~85 °C) versions are available with 4 or 8 GB LPDDR4 and 64, 128 or 256 GB UFS, under the part numbers LEC-RB5-4G-64G-CT/-ER, LEC-RB5-4G-128G-CT/-ER, LEC-RB5-8G-128G-CT/-ER and LEC-RB5-8G-256G-CT/-ER.
