Replacement:<\/strong> None. We are no longer carrying the uLog in our catalog. This page is for reference only.<\/p>\n\n The uLog is a tiny analog datalogger. Central to the logger is an ATtiny24 mated with an AT45DB161D 16Mbit flash IC. Sampling at 50Hz, it\u2019ll log 3 channels of 10-bit ADC for about 2 hours before the memory fills up.<\/p>\n\n Very stripped down and simple to use: at power up it determines if a UART line is attached. If there is, it spits out a \u201c?\u201d and waits for user input. There are only 2 commands: \u201cr\u201d for read and \u201ce\u201d for erase. Erasing the flash sets all addresses to 0xFFFF, and reading dumps all the data up to the first 0xFFFF. If there\u2019s no UART line attached it starts sampling. If connecting with one of our FT232 breakout boards, all you need is TX, RX and ground. If using an RS232 shifter board you will also need to connect 3.3V.<\/p>\n\n The power input is a 2-pin JST connector, which works well with our LiPo batteries, especially the small 100mAh LiPo<\/a>, and it draws just 4mA with an ADXL320 MEMS accelerometer attached. An ON\/OFF switch is also included.<\/p>\n\n There are so many uses for this device! We strapped it to a rocket<\/a> while it logged the analog output of an ADXL321 accelerometer.<\/p>\n\n Features:<\/strong><\/p>\n\n Documents:<\/strong><\/p>\n\n\n
