RV32M1-VEGA Development Board
1. Introduction
This guide describes the hardware for the RV32M1-
VEGA Development Board. The RV32M1-VEGA
development board is a small, low-power, and cost-
effective evaluation and development board for application
prototyping and demonstration of the RV32M1 device.
These evaluation boards offer easy-to-use mass-storage-
device mode flash programmer, a virtual serial port, and
standard programming and run-control capabilities.
The RV32M1 is an ultra-low power, highly integrated
single-chip device that enables Bluetooth Low Energy
(BLE), Generic FSK (at 250, 500, 1000 and 2000 kbps) or
IEEE Standard 802.15.4 with Thread support for portable,
extremely low-power embedded systems.
The RV32M1 integrates a radio transceiver operating in
the 2.36 GHz to 2.48 GHz range supporting a range of
FSK/GFSK and O-QPSK modulations, an ARM Cortex-
M4 CPU, ARM Cortex-M0+ CPU, RISC-V RI5CY CPU,
RISC-V ZERO_RISCY CPU, 1.25 MB Flash and 384 KB
SRAM, BLE Link Layer hardware, 802.15.4 packet
processor hardware and peripherals optimized to meet the
requirements of the target applications.
