This ambiq micro Apollo EVB Microcontroller Development Kit is brand new and comes with the Apollo Evaluation Board and a USB cable.
The new suite of Apollo MCUs is based on the 32-bit ARM Cortex-M4 floating point microcontroller and redefines ‘low power’ with energy consumption that is typically five to ten times lower than that of MCUs of comparable performance (thanks to Ambiq’s patented Subthreshold Power Optimized Technology platform).
On-board user interfaces include 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 evaluation board integrates an on-board hardware debugger together with a complete 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 stand-alone 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 the single micro-USB cable from either a PC USB port or via a DC adapter 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 2.0V or 3.3V with selection via a jumper setting using the on-board voltage regulators or via the external battery connector. Additionally, the board offers split power rails for the Apollo MCU and expansion connector peripherals enabling individual power sources and simultaneous current measurements on both rails.
