BOT40-II
FEATURES

power jumper
+ voltage REG1
+ heat sink

PRG header for OOPic
parallel programming,
or PIC micro ICSP

(physically separate logic and
servo ground busses reduce EMI)

power input
+ charger input

power jumper
+ voltage REG2 (adj)
+ heat sink

Serial EEPROM
9 digital I/O, or
up to 8 A/D

Proto Area

8 digital I/O, or
up to 8 servos

4 LEDs (configurable)

SPI-I²C buss header

MAX232 chip
+ RS-232 header

8 digital I/O, or
up to 8 servos

(configurable power
and ground busses
on all headers)

(I/O lines have pulldown terminations and series
R's for overvoltage and
current-limit protection)

Small 3.6"x3.0"

DB09-F RS232
connector

PIC micro
or OOPic

4 digital I/O, or
up to 4 servos

Physical dimensions: 3.6" x 3.0" (91 x 76 mm).

Configurability. The BOT40-II is highly-configurable:

the proto area can mount different combinations of chips and signal conditioning circuitry for the 8 A/D channels.

a second MAX232 channel and 4 LEDs can be configured to best suit particular user applications.

VREG2 can be a fixed or adjustable regulator, eg LM317 (1 Amp) or LM1084 (5 Amp).

all headers have 3-rows, with configurability of 2nd and 3rd rows for power and ground connections.

can interface up to 21 servos simultaneously with 8 A/D channels, or upwards to 29 servos possible.
