Sunrise Siskin BLHeli_32 21amp and 33amp ESCs

Selling a few Sunrise Siskin BLHeli_32 ESCs. I have them in both 21 amp and 33 amp versions. These feature the all new BLHeli_32 ESC firmware for ESCs that utilize 32-bit MCU (STM32F0 Cortex-M0 at 48MHz), unlike BLHeli and BLHeli_S ESCís that runs on 8-bit processors. BLHeli_32 does not work with 8bit Atmel or Silabs ESCís. With the increased in processing power, faster input signals with lower latency and higher update rate would be possible in BLHeli_32, such as Dshot1200 or even faster protocols! You can read more about these exciting features here:

21 AMP:
Product Name: BL-ARM 21A
MCU: ARM 32-bit
Continuous Current: 21A
Peak Current(10s): 26A
LiPo: 2-4s
Programming card: YES
Weight: 2.0 g
Size(PCB): 25x12mm

33 AMP:
Product Name: BL-ARM 33A
MCU: ARM 32-bit
Continuous Current: 33A
Peak Current(10s): 43A
LiPo: 2-5s
Programming card: YES
Weight: 3.0 g
Size(PCB): 29x16mm

Asking 11 each for 21 amp and 13 each for 33 amp

Heya Hmerly.
I was curious if the 33a version has the pad for telemetry?
