Overview
Ameba acts as a wireless network card and connects to the host MCU via UART/SPI/SDIO/USB, providing network access capability to the host.
Advantages
Compatible with multiple interfaces including: UART, SPI, SDIO, USB, and compatible with various host operating systems including: Linux, FreeRTOS, Zephyr
Supports standard wpa_supplicant/cfg80211 architecture, significantly reducing development complexity, Supports P2P and NAN.
The device side and the host side can run TCPIP in parallel, with the device-side TCPIP used to provide the necessary keepalive mechanisms to avoid frequent wake-ups of the host side.
The device can maintain a connected state with low power consumption in the tens of microamperes and quickly wake up to enter the transmit-receive state.
Typical Applications
Smart Home
- Extends Wi-Fi capability to the main MCU of major appliances (air conditioners, refrigerators, washing machines), small appliances (robot vacuums, air purifiers, smart sockets), and sensing/control devices (wireless sensor nodes, smart locks, lighting systems).
- The device-side protocol stack handles heartbeat and cloud keep-alive, allowing the main MCU to sleep and reduce overall power consumption.
- Supports direct discovery and communication, enabling local ad‑hoc networking and rapid provisioning.
Industrial Sensing & Data Acquisition
- Provides industrial sensor nodes with flexible intermittent connectivity and batch data reporting capabilities, adapting to various field interface requirements.
- Supports ad-hoc communication in router-less scenarios, enabling quick setup of temporary networks for data exchange among field devices.
- Features microamp-level low-power standby, meeting long-term stability requirements for battery-powered applications.
Rapid Network Expansion for Embedded Systems
- Quickly adds network functionality to embedded products (RTOS-based or bare‑metal) without replacing the main MCU, significantly shortening development cycles.
- Serves as a wireless backup or supplementary link for existing wired network devices, enhancing connection reliability.
