Ambiq Micro has released a duo of evaluation kits to enable engineers to assess the capabilities and low-power performance of the Apollo sub-threshold microcontroller: the ‘Apollo EVB’ evaluation board and the ‘Apollo EVK’ evaluation kit.
A key feature of the primary kit, the EVB evaluation board, is the integration of an onboard hardware debugger together with a complete Software Development Kit (SDK). In addition, the system also comes with FreeRTOS, all the necessary hardware drivers, plus a wide selection of code examples to enable quick and effective hardware and software evaluation, development, debug and prototyping.
The Eclipse based graphical software Integrated Design Environment (IDE) and the Open On-Chip (OpenOCD) debugger command-line terminal interfaces run without any external modules or hardware. However, external support is available via a standard 10-pin ARM connector for debugging with other third-party tools such as Keil, IAR, Segger or Lauterbach.
The baseboard’s AM-Link mode also enables it to operate as a standalone debugger for an external target/prototype system for in-circuit debugging. Also included is a serial wire output (SWO) channel, which supports Instruction Trace Macrocell (ITM) debug output information.
The EVB system can be powered via a single micro-USB cable from either a PC USB port or via a DC adaptor included in the kit, with further options for connecting to an external battery or power supply. There is a choice of system operation at either 2,0 V or 3,3 V with selection via a jumper setting using the onboard voltage regulators or via the external battery connector.
The EVB has several onboard user interfaces including three user pushbuttons, an MCU reset pushbutton, four user LEDs, and a serial-wire-debug activity LED. The baseboard also includes four female expansion card connectors in individual 2x14 pin arrays, which also function as header test points. The baseboard also features an additional right-angle 2x14 header connector for attaching smaller expansion cards.
The second kit, the Apollo EVK evaluation kit, adds further functionality and comprises the EVB board system plus add-on modules that include a Bluetooth Low Energy (BLE) add-on card and a Sensor Expansion Card. The Sensor Expansion Card comes pre-populated with a host of different sensors including a number of three-axis accelerometers and gyroscopes and a magnetometer, along with 128 MB of serial Flash memory for storage of sensor data. This modular board also allows additional radios and/or sensors to be added either via a fly-lead approach or via alternate add-on boards.
