FingerTech tinyESCs pack the most power into the smallest package! They take up very little space but can handle more than enough motor current for your robots.
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!
Features:
- Bi-directional brushed motor controller.
- Ultra-compact and lightweight.
- Undervoltage, overcurrent, overtemp reverse-polarity, and BEC protection.
- Internal BEC (battery eliminator circuit) provides 5V to receiver - no extra receiver battery required!
- Calibrate function allows precision driving.
- Status LEDs for both directions and calibration.
*The tinyESC includes a Battery Eliminator Circuit. If there is no 5V supply present on the robot, this will power the radio receiver from the main battery. There is a blocking diode in v2.4 and higher, so multiple tinyESC BECs can be run at once, along with one non-tinyESC BEC (like in a weapon motor controller).
*If you are controlling the tinyESC from a powered device (like Arduino, etc), there is now no worry about damaging the tinyESC from higher voltages.
*Includes 0.01uF capacitor. Solder between motor leads to filter motor noise and voltage spikes. (Not required for FingerTech Spark motors - they are high quality and do not generate dangerous voltage spikes.)
FingerTech tinyESC v2
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 (see Videos tab).
BEC Output: 5V, 100mA (can run other electronics like receivers and other ESCs, but not motors or servos. Receivers with telemetry 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!
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 (needs capacitor)
- 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)
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
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!]
Currently there are three two known 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 included capacitor). High-efficiency motors like Maxon brand can create voltage spikes on reversing so the capcitor is needed on those as well.
-FingerTech Spark motors are not noisy and do not need the capacitor.
