1 Hardware Introduction
DB-G2L-V2 is a high-performance industrial development board based on the industrial-grade
Renesas RZ/G2L dual-core ARM Cortex-A55 + single-core ARM Cortex-M33 heterogeneous multicore
processor design, consisting of a core board and a backplane. the ARM Cortex-A55 main processing unit
clocked at 1.2GHz, integrates the latest high-performance ARM Cortex-A55 main processing unit with
1.2GHz, integrated with the latest high-performance CPU and GPU, and also adopts a security island
with Cortex-R5 dual-core lock-step mode, which can be applied to scenarios with stringent requirements
on security performance.
The development board is rich in interface resources, leading to a dual-channel network port, 2x
CAN-bus, 3x USB2.0, multiple serial ports, on-board USB WiFi module, support for 4G module, while
leading to MIPI LCD, CAMERA, RGB LCD, LINE IN, LINE OUT, MIC IN and other audio and video
multimedia interfaces, so that the user can quickly carry out the evaluation of product solutions and
technology pre-research. and technology pre-study.
