AquaTimer is a programmable timer for 12V devices such as lighting, solenoid valves or pumps not only for aquariums. It has three switchable channels for currents up to 2A each and up to 5A in total. Connected lighting can be dimmed if desired and slowly faded in and out to simulate sunrises and sunsets. The internal RTC of the ATtiny is used as a clockwork in conjunction with a 32.768kHz crystal. A backup battery keeps the clock running even if the external power supply is interrupted. Settings are made using three buttons and the OLED display.

Compact surface-mount production variant of the fixed-function, crystal-referenced low-power burst timer. Electrically equivalent to the through-hole version where practical, with selectable interval, duration, carrier frequency, AUTO/TEST mode, ENABLE output, and gated OSC_OUT; no MCU, firmware, PLL, VCO, or programmable logic.

The Atmel® | SMART SAM9260, manufactured by Atmel, is an ARM-based Embedded Microprocessor Unit (MPU), integrating the ARM926EJ-STM processor operating at 180 MHz. This MPU includes substantial on-chip memory and extensive peripherals, including an Ethernet MAC, USB Device and Host Ports, along with various standard interfaces such as USART, SPI, TWI, Timer Counters, and MultiMedia Card Interface. Architected on a 6-layer matrix delivering a maximum internal bandwidth of six 32-bit buses, it supports external 32-bit bus interfaces for SDRAM, static memories, CompactFlash, and SLC NAND Flash with ECC. The SAM9260 is available in 217-ball LFBGA and 208-pin PQFP packages. Key features include 8 Kbytes each of data and instruction cache, integrated MMU, two internal 4-Kbyte SRAMs, a 32-Kbyte ROM with bootloader, 22 Peripheral DMA channels, various power-on reset modes, two programmable clock signals, advanced interrupt controller, and multiple power management options for optimized performance and energy efficiency.
