Specifications:
Battery Voltage: 6.5V - 36V
Motor Current: 1.5A continuous (forever). For robots, usable continuous current is 2.0A.
Max Current: 3A. For robots though, 5A-stall motors are easily handled by tinyESCs (seeVideostab).
BEC Output: 5V, 100mA (can run other electronics like receivers and other ESCs, but not motors or servos. Receivers with telemetry [such as the FS-IA6] require a stronger/separate BEC.)
BEC current is reduced for voltage above 8V - see graph:BEC Derating Graph.
Frequency: 1953Hz (v2.6 and above), 976Hz (v2.5 and below).
Motor is braked to stop rather than coasting. This gives precision motor control, crucial for robot drive!
Available withMiniQD Connectorsinstalled - these clip onto motor terminals (Spark and other FK050 motors) and eliminate the need for soldering!
Motors that our customers regularly run off a single tinyESC:
- 2 Gold/Silver Sparks 16mm up to 18.5V
- 2 Maxons 13mm up to 18.5V
- 3 BotBitz/Pololu/Sanyo 12mm
- 1 Kitbots 1000RPM 25mm up to 11.1V (needscapacitor)
- 1 B16 22mm up to 11.1V (2.5A stall)
- 1 B62 22mm up to 11.1V (5A stall)
- 1 BotKits 22mm up to 11.1V (5A stall)
*Note: Multiple motors on a single tinyESC can not be independently controlled. A standard drive would require 1 ESC per side, driving 1-3 motors each.
Dimensions:
Circuit board size: 1.27x1.27x0.41cm (0.5x0.5x0.16”)
Outer heatshrink size: 1.35x1.85x0.48cm (0.53x0.73x0.19”) - calibration pins have been changed from male to female in v2.4 and removed entirely in v2.5 to reduce length and fragility
Wire guage: 26AWG
Weight with wires: 3.7grams (0.14oz)
Weight without wires: 0.6grams (0.02oz) [We don't know why you would ever need weight without wires, but other companies seem to think it's a selling point, so here it is to compare with!]
Built-in Protection:
Currently there arethreetwoknown ways to destroy a tinyESC. (So avoid them!)
1) Reverse battery voltage.Not anymore!
2) Applying battery voltage to the motor outputs.
3) Voltage spikes from noisy motors (not using the includedcapacitor). High-efficiency motors like Maxon brand can create voltage spikes on reversing so the capacitor is needed on those as well.
-FingerTech Spark motors are not noisy and do not need the capacitor.
Previous code revisions:
Version 2.6: A code re-write from the bottom up has things running faster and smoother, with a more intuitive Calibration routine.
Version 2.5 does away with the calibration header and jumper. Now, to enter the calibrate routine at any time you simply short the calibrate pads. Short them once again when you are done and the routine saves and exits!
Version 2.4 introduced backwards-polarity protection - plugging a battery in backwards will not destroy a tinyESC! There is also now protection on the 5V receiver line so that other BECs will not affect the tinyESC - no need to disconnect the red wire anymore!
