Software / GCS Support:

The software solution is an open source development called "SiK". It has been re implemented to suit the new processor architecture available on the 32bit ARM processor core. A boot loader and interface is available for further development and field upgrade of the modem firmware via the serial port. Most parameters are configurable via AT commands, Eg. baud rate (air/uart), frequency band, power levels. Integrated support for configuring the RFD900 radios is supported by APM Planner. The default settings are at 57600 baud, N, 8, 1, and 200k air data rate. The RFD868ux manual is here: RFD900ux Manual The RFD868ux SiK software manual is here : RFD900x Peer-to-peer Manual

Software features include:

  • Frequency hopping spread spectrum (FHSS)
  • Transparent serial link
  • Point to Point networking
  • Configuration by simple AT commands for local radio, RT commands for remote radio
  • User configurable serial data rates and air data rates
  • Error correction routines, Mavlink protocol framing (user selectable)
  • Mavlink radio status reporting (Local RSSI, Remote RSSI, Local Noise, Remote Noise)
  • Automatic antenna diversity switching on a packet basis in real time
  • Automatic duty cycle throttling based on radio temperature to avoid overheating

Compliance:

The modem is designed for system integrators who will integrate the modem into their own projects and product prototypes. The user is responsible for compliance with local regulations for radio transmitters.

Great scale that needs some improvements to be perfect
Color: White, Color: White
Very accurate scale, looks good in white, timer works nicely and I do like the concept of the ratio conversion. Shown in photos with 0 measurement drift over time, even without the silicone mat. To make this the best scale in the price range, I would change: - The auto timer function. Timing currently stops if you pick up the brew to swirl; you must completely restart the process if you do happen to pick it up. I would change that to only stop on user input (pressing a button). - The ratio conversion. Why offer XX.0 precision if you can only change the ratio in whole amounts? I'd suggest offering 0.1 increments, selectable with +/- buttons instead of cycling through. - The silicone mat is not well affixed and slides around. Kind of useless as-is and I just keep it off. I would wrap the whole thing around the measurement platform, similar to how the Greater Goods scale does it, to really keep it secure. It's not perfect, but for the price, it's a 4.5/5 for me. Rounding up to 5 since a 4 is considered "bad" by today's online rating standards.

IMO, a filter coffee lovers best scale option on a budget. Solid grade A choice.
Color: Black
I have two other .1mg "coffee" or food scales that I used regular for pour overs. I saw this has 4x display on real time flow rate, g/mg weight, timer, and grounds to water ratio for a solid price and purchased this after reading some reviews. One of my scales has these features, but the workflow on this scale just clicked a ton better for me. The beep isn't super loud annoying which is a major relief, as I just couldn't keep sound on on my other scale due to that trigger honestly. I tried brew mode immediately and will now only use that when making a pour over. Loved the beep alerting when I finally hit the proper ratio and I like it keeps my final info on screen after the brew for my study. I can actually practice my technique now and not have split attention as much. This is still compact, but fits a larger carafe well whereas my other scale is a better fit for the espresso machine. The display is clear and buttons have a slight tactile sensation from the print, but are still the capacitive touch based style. I tested it with weights and it is my most accurate scale, it hit the .1g accurately every time or at worst would fluctuate back and forth quickly from the true value (more than enough for me to trust it). It updates and tares from power on fairly fast, it reacts fast enough to touch to not make me pause much. My nitpicks are that the front clear matte plastic isn't quite uniform flat viewed at an off angle giving it a cheaper look, but that doesn't affect functionality at all and truth is, it really was very affordable for the feature set I feel. The second nitpick was that the scale's mat does not grip well or fit securely over prompting it to move around easily. For this I had to modify using some rubberized grip tape on the surface of scale underneath the mat itself. Now it doesn't slide from vibration and if any pressure down it doesn't slip. I could have removed it totally, but it is attractive and useful once stabilized. With that modification done, I can fully recommend this scale for filter coffee lovers at any price. Great product, hopefully lasts me a long time.
