Description

SparkFun OpenLog ArtemisThe SparkFun OpenLog Artemis is an open source data logger that comes preprogrammed to automatically log IMU, GPS, serial data, and various pressure, humidity, and distance sensors. All without writing a single line of code! OpenLog Artemis, or "OLA," automatically detects, configures, and logs Qwiic sensors. The OLA is specifically designed for users who just need to capture a lot of data to a CSV and get back to their larger project.

The OLA is specifically designed for users who just need to capture a lot of data to a CSV and get back to their larger project.

&feature=emb_title

Included on every OpenLog Artemis is an IMU for built-in logging of triple-axis accelerometer, gyro, and magnetometer. Whereas the original 9DOF Razor used the old MPU-9250, the OpenLog Artemis uses the latest ICM-20948 from InvenSense capable of nearly 250Hz logging of all nine axes. Simply power up the OpenLog Artemis and all incoming serial data is automatically recorded to a log file with baud rates up to 921600bps, supported! The OLA also has four ADC channels available on the edge of the board. Voltages up to 2V can be logged with 14-bit precision up to 1900Hz for one channel and 1000Hz logging all four channels. Additionally, based on feedback from users we've added an on-board RTC so that all data can be time stamped.

The OpenLog Artemis is highly configurable over an easy to use serial interface. Simply plug in a USB-C cable and open a terminal at 115200bps. The logging output is automatically streamed to both the terminal and the microSD. Pressing any key will open the configuration menu.

The OpenLog Artemis automatically scans, detects, configures, and logs various Qwiic sensors plugged into the board (No soldering! No programming!). So see the latest list of auto detect supported modules, please see the Sparkfun website.

This OpenLog uses common microSD cards to record clear text, comma separated files. You probably already have a microSD card laying around but if you need any additional units see the related items below. The OpenLog Artemis supports microSD cards formatted as FAT32 as well as the older FAT16 formats up to 32GB. Currently, the OpenLog Artemis does not support microSD cards formatted with exFAT but we plan to offer support for it in the future

Very low power logging is supported. OpenLog Artemis can be configured to take readings at 500 times a second, or as slow as 1 reading every 24 hours. You choose! When there is more than 2 seconds between readings OLA will automatically power down itself and the sensors on the bus resulting in a sleep current of approximately 18uA. This means a normal 2Ah battery will enable logging for more than 4,000 days! OpenLog Artemis has built-in LiPo charging set at 450mA/hr.

New features are constantly being added so we've released an easy to use firmware upgrade tool. No need to install Arduino or a bunch of libraries, simply open the Artemis Firmware Upload GUI , load the latest OLA firmware, and add features to OpenLog Artemis as they come out!

The OLA can be tailored to many different applications and we will be releasing custom versions of the firmware which can be found in the documents section below.

Order it! Its great
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
I love the texture! Its silky smooth and light on the skin, no weird smell, very moisturizing. Ive used one of the containers for most of my pregnancy to keep the skin on my belly and hips moisturized. I add a few drops of organic frankincense to a nickel-sized amount of this balm and mix it together in my hands before applying. I use a clean q-tip to scoop out the tallow balm as needed too to be sure the rest in the jar stays clean, rather than using my washed fingers, to reduce accidentally contaminating the rest of it somehow. My skin has stayed so healthy thanks to this product. It reduces the itchiness of my expanding skin from the baby growing in my belly, and i think its made a positive difference in preventing stretch marks by keeping my skin hydrated as i use it almost daily and after every shower. I just got my second jar in the mail to use for this last month of my pregnancy, and I will probably use it for my baby when hes born too. I also love that it comes in nice packaging, with a thank you note, very minimal plastic, and classy label. I dont think the jar is plastic either which i LOVE (pretty sure its glass container?) Thank you to the creators of this product. I kind of wish i could get it in a glass dispenser like lotion but i really dont care at the end of the day. Its amazing. You should try it.

Smells nice and light
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
Nice and creamy. Feels silky. Unfortunately, it does not help my knuckles very much. But I would buy it again because it is a good cream.

Excelentt
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1), Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
This product is really good, I researched it because it is the closest to human skin, and that was what it did help me repair my skin that was injured after an allergy of more than two months. I felt that I had lost the elasticity and shape of my skin, this fat stuck to me and made me feel safe again.

Will repurchase
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
At 56 years old my skin is pretty dry but this was still a little to heavy for a face cream-- but usable in a pinch. What it is PERFECT for is for your hands before you go to sleep at night. You know you're going to touch your face and pillow during the night so heavily fragranced creams aren't good at all. This is thick enough to make your hands and cuticles feel great but gentle enough not to cause problems if transferred onto your face.

Soft and Smooth!
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
This product feels fantastic when you put it on. A little goes a very long way so you get a lot for your money. It does work great after just lightly drying your face. There isn’t much of a smell, which I prefer. I have very sensitive skin and this is so soothing to use. I’m also in my late 40’s so the soft, plump and smooth look achieved after using this is so nice. If it makes your skin greasy at all you are using too much.
